Bending Moment Apparatus (Product Code: SLE/MCE/23) is a hinged-beam test rig used to measure the shear force and bending moment at a beam section under different loads in strength of materials and structures laboratories. Its 1 m span teak wood beam is made of long and short sections joined by a hinge, and spring balances with adjusting screws measure the internal forces while a spirit level returns the beam to its original position. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Bending Moment Apparatus Used For?

Shear force and bending moment diagrams are central to beam design, yet students rarely see those internal forces measured. Here the beam is divided at a section and bridged by a hinge, so the forces at that section have to be carried by the spring balance arrangements. After hanging loads at chosen positions, students turn the adjusting screw until the spirit level shows the beam back in its original position, read the spring balance and use the fixed lever distance to work out the bending moment; a similar reading at the hinge gives the shear force.

Comparing these measured values with hand calculations from statics confirms the theory for loads at different positions. Moving a single load step by step across the span and plotting the reading at the section builds the influence line diagram, a topic civil and mechanical students often find abstract on paper. With the technical manual guiding each experiment, it is practical engineering lab equipment for colleges and polytechnics in India.

The Bending Moment Apparatus is manufactured by ScienceLab as the OEM. Jain Scientific Equipments Private Limited, the registered company behind the ScienceLab brand, makes it at its own licensed factory at Saha, Ambala, Haryana, India, and supplies it factory-direct to engineering colleges, polytechnics, dealers and importers.

Friction Slide Apparatus (Product Code: SLE/MCE/24) is a bench-top inclined-plane apparatus used to measure the coefficient of friction between pairs of materials in mechanics and theory of machines laboratories. Its ground steel plane locks at any angle within ±45° on a protractor scale, and two composite slider trays let students compare aluminium, steel, nylon and brass surfaces. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Friction Slide Apparatus Used For?

Each slider tray is tied to a weight hanger by a cord that runs over the pulley, and weights are added until the tray just begins to slide up the steel plane. The hanging load at that moment, compared with the tray's weight and the plane angle, gives the coefficient of static friction for that material pair. Loading extra weight into the tray shows students that friction force rises in proportion to the normal force.

Because the plane locks anywhere within ±45°, the same set-up doubles as an exercise in equilibrium of forces on an inclined plane apparatus, resolving weight into components along and normal to the surface. Keep the steel plane and tray faces clean and dry, start each trial from the same position and repeat readings to average out scatter. It is compact mechanics lab equipment in India that suits both engineering and senior physics classes.

Four Bar Chain Apparatus (Product Code: SLE/MCE/25) is a kinematics teaching unit used to show how a four-bar linkage converts uniform continuous rotation into non-uniform rotation or oscillation, in theory of machines laboratories. Students reposition its pivot joints to change crank radius, oscillation radius and coupling length, then read input and output angles on built-in scales to compare crank-rocker, double rocker and double crank mechanisms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Four Bar Chain Apparatus Used For?

Four-bar linkages sit inside windscreen wipers, rocking conveyors, pump jacks and countless machine mechanisms, and this unit lets students see exactly how one works. The class turns the drive disk in equal steps, notes the input angle on its scale and reads the matching output angle on the output disk. Plotting output against input reveals the non-uniform motion, the limits of oscillation and the dead-centre positions of the linkage.

Changing the pivot positions then shows how link proportions decide whether the linkage behaves as a crank-rocker, double rocker or double crank — the Grashof condition taught in lectures. Work gently near the extreme positions, tighten the pivots after each change and keep a sketch of every configuration with its readings. For departments sourcing mechanics lab equipment in India, it is a stackable, portable unit that serves several groups in turn.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Four Bar Chain Apparatus. It is produced and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to engineering colleges, polytechnics, technical training institutes, dealers and importers.

Because you deal with the maker, questions about link parts, pivots or matching units for additional benches get answered at source — just ask us. See the ScienceLab profile for company details.

Cantilever Beam Apparatus (Product Code: SLE/MCE/26) is an L-shaped stainless steel frame used to study moments and the equilibrium of a loaded cantilever arm in engineering mechanics and structures laboratories. A graduated 75 cm horizontal arm carries a sliding slotted weight set from 100 g to 1 kg, while a 10 kg spring balance holds the arm horizontal under any load. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Cantilever Beam Apparatus Used For?

Students hang slotted weights at chosen graduations along the 75 cm arm and adjust the spring balance until the arm is exactly horizontal again. Because the arm is level, the lever distances can be read straight from the graduations, and the spring balance reading gives the force needed to hold the loaded arm in equilibrium. Taking moments and comparing the calculated force with the balance reading verifies the principle of moments for a cantilever-type member.

Repeating the test with different weights and positions produces a set of readings for a graph of balance force against applied moment, which should form a straight line. The stainless steel frame stands up well to daily use in a teaching laboratory, and the simple analog reading suits first-year classes. It is a compact addition to mechanics lab equipment in India for civil, mechanical and polytechnic courses; always bring the arm back to horizontal before recording each reading.

OEM Manufacturer

ScienceLab is the OEM for the Cantilever Beam Apparatus. The frame is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab, at its own licensed factory at Saha, Ambala, Haryana, India, and is supplied straight from the factory to schools, colleges, dealers and importers.

Gear Trainer Demonstrator (Product Code: SLE/MCE/27) is a sliding mesh gearbox demonstrator used to teach how gear ratios change speed and torque through a transmission, in automotive and theory of machines laboratories. It represents a typical three forward ratio and reverse sliding mesh box, with protractor pulleys on the input and output shafts so students can determine and verify velocity and torque ratios. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Gear Trainer Demonstrator Used For?

The sliding mesh box is seldom found on modern cars and survives mainly on heavy commercial vehicles, yet its layout is the one from which most modern gearboxes were developed. That makes it the clearest starting point for students of automobile engineering and machine design. With each ratio engaged in turn, the class turns the input pulley through a measured angle, reads the output rotation on the second protractor and works out the velocity ratio.

Applying known loads at the pulleys then lets students compare torque ratio with velocity ratio and discuss losses between them. Counting teeth to predict each ratio before measuring it is a good check, and the reverse gear shows how an extra gear changes the direction of output rotation. The demonstrator works equally well at the front of a lecture room or on a practical bench, which makes it versatile engineering lab equipment for technical institutes.

What to Specify When Ordering

• Number of demonstrators for lecture and practical use
• Whether you also need an Overdrive and Differential to build a simple transmission — confirm availability with us
• Delivery destination in India or abroad

OEM Manufacturer

Gear Train Model (Product Code: SLE/MCE/28) is a mechanism model used to demonstrate a differential gear train built entirely from spur gears, in theory of machines and automobile engineering laboratories. It combines two planetary gear trains whose sun gears are coaxial, so students can hold either wheel and watch how the remaining gears keep turning. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Gear Train Model Used For?

A differential lets two outputs turn at different speeds from one input, which is why a vehicle's wheels can take a corner without scrubbing. Textbook diagrams can make this hard to picture; this model shows the same function with spur gears only, arranged as two planetary trains sharing a common axis. Holding one wheel fixes its sun gear, and students can watch the other gears keep turning and relate what they see to the kinematic equations of planetary trains.

A good exercise is to drive the model slowly, count output turns with one wheel held and then the other, and compare the results with calculated values. The model also illustrates mechanisms that need two controllable inputs, a topic that links theory of machines with robotics and control. Handle it at low speed and keep fingers clear of meshing gears. It is well suited as engineering lab equipment for demonstration tables and student practicals alike.

OEM Manufacturer

The Gear Train Model is manufactured by Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which trades as ScienceLab and is the OEM (original equipment manufacturer) of this model. Production takes place at the company's licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414).

Colleges, training institutes, dealers and importers buy it factory-direct, so quotations, repeat orders and questions about replacement gears are handled by the manufacturer — ask us. More background is on the ScienceLab company profile.

Frequently Asked Questions

What mechanism does the Gear Train Model show?
The Gear Train Model shows a differential gear train in which all the gears are spur gears. It is built as a combination of two planetary gear trains whose two sun gears are coaxial, demonstrating differential action without bevel-gear complexity.

What happens when one wheel of the Gear Train Model is held?
When the right wheel of the Gear Train Model is held, the right sun gear becomes fixed while the other gears can still rotate; holding the left wheel fixes the left sun gear in the same way. With both wheels free, all spur gears run.

Where is the principle of the Gear Train Model applied?
The Gear Train Model illustrates mechanisms for situations that require two controllable inputs, as well as the familiar vehicle differential. Students can link its behaviour to planetary gear train theory covered in theory of machines courses.

The blocks come in five shapes, two sizes, two thicknesses and three colours, packed in a storage tray whose shape sorter doubles as a tracing template. Part of our mathematics lab kits for India and abroad, it is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Attribute Blocks Desk Set Used For?

Each block differs from the others in four attributes, shape, size, thickness and colour, and with sixty pieces every combination appears exactly once, which makes the set well suited to logical sorting. Children group blocks by one attribute and then by two, build "one-difference" trains where each block changes in only one way from the last, and describe pieces precisely, such as "the thick, large, red one". The same blocks support counting, comparing sizes and repeating patterns.

The shape sorter in the storage tray gives every piece a place to go, so packing away becomes a matching task in itself, and pupils can trace the sorter openings to draw shapes in their notebooks. For group work, split the blocks between tables and ask each group to invent a sorting rule for the others to guess. Wipe the plastic blocks with a damp cloth to keep them clean between classes.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Attribute Blocks Desk Set and produces it at its licensed factory at Saha, Ambala, Haryana. Schools, teacher-training institutes, dealers and importers in India and international markets order it factory-direct, often as part of a complete mathematics lab, and every quotation comes straight from the manufacturer.

Pulley Demonstration Set (Product Code: SLE/MCE/29) is a free-standing pulley rig used to demonstrate mechanical advantage, velocity ratio and efficiency with fixed and movable pulleys in school and college mechanics laboratories. Physics teachers and engineering instructors use it to build anything from a single pulley to quadruple-sheave systems on three 81 cm steel rods, loaded with brass slotted masses. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as a complete pulley system lab set in one order.

Specifications

What Is the Pulley Demonstration Set Used For?

Collars with hooks slide onto the horizontal rod to carry the pulleys, and the right-angled clamps hold that rod across the vertical rods. A brass weight hanger carries the load, and slotted masses are added on the effort side until the load just rises. Comparing load with effort gives the mechanical advantage; measuring how far the effort and the load travel gives the velocity ratio, and the two together give the efficiency of the arrangement.

Because the kit contains single, triple tandem and quadruple pulleys plus a wheel and axle, one set covers the whole progression from a simple fixed pulley to block-and-tackle systems and other simple machines, making it practical mechanics lab equipment in India for beginner and advanced classes alike. The base also carries a capstan and an eye hook for cord arrangements. Before loading, tighten the vertical rods with the tommy bar, keep the cord running squarely in each groove and add masses gently so that swinging does not upset the readings.

What to Specify When Ordering

• Number of complete sets needed for your student groups
• Extra cord rolls, if classes re-string the pulleys often (4 rolls come with each set)
• Additional slotted brass masses or weight hangers beyond the standard assortment
• Spare single, triple tandem or quadruple pulleys for replacement
• Delivery location in India or abroad
