Free and Forced Vibration Apparatus (Product Code: SLE/MCE/76) is a vibration trainer used to study free, damped and forced mechanical vibration of a bar-type oscillator in mechanical engineering laboratories. Its electronically controlled exciter runs from 0 to 50 Hz, an oil-filled hydraulic damper gives adjustable damping, and a mechanical drum recorder traces each response on paper. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Free and Forced Vibration Apparatus Used For?

The bar-type oscillator works together with interchangeable coil springs and, depending on the experiment, is left to vibrate freely, slowed by the oil damper, or driven by one of the two exciters. In free vibration tests, students displace the bar, release it and use the drum recorder trace to find the natural frequency; with the damper connected, the decay of successive peaks gives the logarithmic decrement and damping ratio. Changing between the 0.75, 1.5 and 3.0 N/mm springs shows how stiffness shifts the natural frequency.

For forced vibration, the control unit sets the excitation frequency up to 50 Hz, driving the bar through either the imbalance exciter (0–1000 mmg) or the displacement exciter (20 mm stroke). Stepping through the range and recording amplitude reveals resonance, and repeating the sweep at several damper settings shows how damping flattens the resonance peak. This makes the unit core engineering lab equipment for dynamics of machinery courses in India; let the exciter settle at each frequency before taking a trace.

Corollis Component of Acceleration Apparatus (Product Code: SLE/MCE/77) is a self-contained water-jet rig used to determine the Coriolis component of acceleration at different rotation speeds and water flow rates in theory of machines laboratories. Water leaves rotating arms with 9 mm and 6 mm orifice diameters, while a 250–2500 LPH rotameter shows the flow and a variable-speed swinging-field motor sets the speed. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Coriolis Acceleration Apparatus Used For?

When a body moves outward along a link that is itself rotating, it gains an extra acceleration at right angles to the link, equal to twice the product of the angular velocity and the sliding velocity. This is the Coriolis component, a key idea in the kinematics of slotted-link and quick-return mechanisms. In this apparatus the moving body is water flowing out along the rotating arms, which makes the effect measurable in a classroom.

A typical session holds the flow steady on the rotameter, runs the arms at several speeds with the speed control unit, then repeats at other flow rates, so students see how the component depends on both angular velocity and flow velocity and compare their results with theory. Because the tank, pump and arms form a closed re-circulating circuit on one powder-coated frame, the rig needs no water supply line, which suits engineering lab equipment rooms in India and abroad. Check the water level before each run and raise the speed gradually.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• Number of units required
• Delivery location, so that the quotation matches your destination

Gyroscope Experiment Manual (Product Code: SLE/MCE/78) is a hand-spun gyroscope apparatus used to demonstrate precession and the gyroscopic couple in theory of machines and physics laboratories. A 250 mm, 1500 g disc runs on dual ball bearings at one end of a tilting shaft, balanced by a movable 1400 g counterweight, and the shaft angle is read on a scale from -40° to +40°. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Gyroscope Experiment Apparatus Used For?

With the disc at rest, students first use the movable counterweight, the spirit level and the thumbscrew to balance the shaft horizontally. They then spin the disc by hand or with the cord and apply the 50 g additional weight to unbalance the shaft: instead of simply dropping, the shaft swings slowly around the vertical axis. This precession is the classic gyroscopic effect, and timing it against the disc speed lets the class compare observed precession with the value predicted from the disc's angular momentum.

Because the dual ball bearings keep the rotation nearly frictionless, the disc keeps turning for long periods, leaving time for several readings from one spin. The open construction lets a whole group watch the shaft's motion, while the inclination scale records how far the shaft tilts. The apparatus links physics lab equipment in India for angular momentum with engineering cases such as the gyroscopic couple on ships, aircraft and vehicles taking a turn.

OEM Manufacturer

ScienceLab is the original equipment manufacturer of this gyroscope. Jain Scientific Equipments Private Limited, known to buyers as ScienceLab, makes it at its own licensed factory at Saha, Ambala, Haryana, India, and dispatches it factory-direct to schools, colleges, dealers and importers.

Static and Dynamic Balancing Apparatus (Product Code: SLE/MCE/79) is a rotating-shaft trainer used to show the difference between static and dynamic imbalance and to practise balancing rotating masses in theory of machines laboratories. Four imbalance masses attach to a smooth shaft at any angular and longitudinal position, and a variable-speed motor with belt drive turns the shaft up to 1400 rpm with a digital speed display. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Static and Dynamic Balancing Apparatus Used For?

A rotor is statically balanced when it stays put in any angular position, yet it can still shake when it spins if its masses lie in different planes along the shaft; that is dynamic imbalance. On this unit, students first arrange the four imbalance masses so the shaft rests in any position, comparing the moment they produce about the shaft with the moment of the imbalance masses. They then run the motor and see whether the shaft turns smoothly or vibrates, which shows why static balance alone is not enough.

The usual exercise is to calculate the angular and axial positions of the masses by the graphical or analytical method taught in dynamics of machinery, set them on the shaft, and confirm the result by running at increasing speed on the digital display. Close the transparent cover before starting the motor and tighten every mass securely. For colleges building a set of mechanics lab equipment in India, it pairs naturally with whirling-of-shaft and vibration apparatus.

OEM Manufacturer

The Static and Dynamic Balancing Apparatus is produced by ScienceLab as the OEM. Jain Scientific Equipments Private Limited, which operates under the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, so universities, polytechnics, laboratory suppliers and importers can buy straight from the source.

Repeat orders and requests for spare imbalance masses or a replacement drive belt are handled by the manufacturer itself; ask us. More information is on the ScienceLab company profile.

Internal Gear Pinion Drive (Product Code: SLE/MCE/80) is a hand-cranked bench-top model used to demonstrate the fundamentals of how an internal gear and pinion drive works in theory of machines and technical training classrooms. The gear train is left open for study between two clear plastic plates, and two dials show rotation so students can compare the movement of the gears. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Internal Gear and Pinion Drive Used For?

In an internal gear drive, a small pinion meshes with teeth cut on the inside of a larger ring gear. Unlike an ordinary external gear pair, both gears turn in the same direction and the centre distance is shorter, which is why the arrangement appears in planetary gearboxes and compact reduction drives. Turning the hand crank slowly lets students watch the teeth engage through the clear plates and see the same-direction rotation for themselves.

Using the two dials, the class can count turns and compare the result with the ratio of tooth numbers, then discuss why internal gearing gives a compact reduction. At 5 kg and 400 x 200 x 300 mm, the model is easy to carry between classroom and workshop, making it handy engineering educational equipment in India for ITI, polytechnic and first-year engineering courses. Wipe the plastic plates with a soft cloth so the mesh stays clearly visible.

OEM Manufacturer

This demonstrator is an OEM product. Jain Scientific Equipments Private Limited, trading as ScienceLab, manufactures the Internal Gear Pinion Drive at its own licensed factory at Saha, Ambala, Haryana, India, rather than reselling a bought-in model.

Training institutes, schools, dealers and importers order it directly from the manufacturer, which also handles repeat orders when more classrooms need the same model. Read more on the ScienceLab company profile.

Whirling of Shaft Apparatus (Product Code: SLE/MCE/81) is a rotor dynamics trainer used to find the critical (whirling) speeds and mode shapes of slender rotating shafts in mechanical engineering laboratories. Six high-strength steel rotor shafts of 3, 6 and 7 mm diameter and 600 or 900 mm length are driven by a 0.37 kW adjustable-speed motor up to 6000 rpm behind a transparent protective cover. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Whirling of Shaft Apparatus Used For?

Every slender shaft has speeds at which it bows outward and whirls, because the running speed coincides with a natural frequency of transverse vibration. Students fit a rotor shaft, raise the motor speed slowly with the potentiometers, and note on the digital display the speed at which the shaft visibly whirls, then compare it with the value calculated from shaft stiffness, mass and support conditions.

Repeating the run with the 3, 6 and 7 mm shafts, the 600 and 900 mm lengths and different bearing spacing shows how diameter, length and support position move the critical speed, while higher speeds reveal the mode shapes of a continuous rotor. The two preselectable speeds make it quick to return to a point of interest. Keep the cover closed and pass steadily through each critical speed; as engineering lab equipment in India for dynamics of machinery, it shows clearly why turbine and pump shafts are designed to run away from their critical speeds.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase
• Spare rotor shafts, if you expect heavy student use (ask us)
• Number of units and the delivery location

Computerized Cooling Tower Test Bench (Product Code: SLE/MCE/83) is a fan-driven cooling tower model used to study the evaporative cooling of water by air in thermal and chemical engineering laboratories. Colleges add this engineering lab equipment because its 150 × 150 mm cooling column holds a wet deck with a specific surface of 110 m²/m³, and a three-stage heater (500, 1000 or 1500 W) sets the heat 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 Cooling Tower Test Bench Used For?

Warm water from the heated circuit is pumped to the column and spreads over the wet deck while air from the fan passes through it; part of the water evaporates and cools the rest. By measuring water and air temperatures, relative humidity, water flow and airflow through the 80 mm orifice, students calculate the cooling range, the approach to wet-bulb temperature, the heat removed and the water lost by evaporation.

Switching the heater between 500, 1000 and 1500 W and changing air and water flows shows how heat load and air-to-water ratio affect performance — the same questions faced in power-station and HVAC cooling towers. Keep the 4.2 L additional-water tank topped up, since evaporated water must be replaced, and remember that the thermostat switches the heater off at 50 °C.

What to Specify When Ordering

• Power supply version: 230 V 50 Hz or 230 V 60 Hz, single phase
• Floor space and headroom for a 1200 × 600 × 1600 mm bench of about 125 kg
• Water filling and draining arrangements at the installation point
• The computerised data-logging arrangement you expect, so it can be confirmed in the quotation
