Rotational Moment of Inertia Apparatus (Product Code: SLE/MCE/30) is a three-string pendulum set-up used to determine the moment of inertia of a rigid body in engineering and physics laboratories. A hanging plate is twisted into torsional oscillation, and a photoelectric sensor with a time counting device measures the oscillation period, so students obtain the period electronically rather than by eye. 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 Rotational Moment of Inertia Apparatus Used For?

Moment of inertia is the rotational counterpart of mass: it describes how strongly a body resists a change in its rotation, and it depends on how that mass is distributed about the axis. Here the plate hangs from three strings, a small twist sets it oscillating about its vertical axis, and the period of that torsional oscillation is linked to the moment of inertia of whatever the plate carries. Timing the empty plate first and then the plate with a test body lets students separate the body's own moment of inertia.

Moving the same body away from the centre of the plate shows how the axis position changes the result, a direct check of the parallel axis theorem in engineering mechanics classes. For consistent readings, keep the twist small, start the plate without sideways swing, and repeat each timing a few times before averaging. As a moment of inertia kit for Indian colleges and polytechnics, it pairs well with a balance and a vernier caliper, because the calculation needs the masses and dimensions involved.

OEM Manufacturer

The Rotational Moment of Inertia Apparatus comes from ScienceLab as the original equipment manufacturer. Jain Scientific Equipments Private Limited, trading as ScienceLab, builds it at its own licensed factory in Saha, Ambala, Haryana, so engineering colleges, universities, distributors and importers buy direct from the maker rather than from a stockist.

The company is a registered MSME with manufacturing as its major activity (Udyam UDYAM-HR-01-0003714), and export consignments are shipped under Importer-Exporter Code AAECJ8618A issued by DGFT. See the ScienceLab company profile for more background.

Related Theory of Machines Equipment

Working out a moment of inertia also needs masses and dimensions, and the topic links to other rotational and torsional experiments:

• Physical Balance (Digital) — weighs the plate and test bodies used in the calculation.
• Caliper Vernier (Metal) — measures plate radius and body dimensions for the theoretical value.
• Stopwatch, Digital — a manual cross-check of the electronic period reading.
• Vibration Of Spiral Spring Apparatus — another torsional oscillation experiment, using a spiral spring instead of strings.

More rotating-mass and mechanism apparatus is listed in the Theory of Machines category.

Frequently Asked Questions

What method does the Rotational Moment of Inertia Apparatus use?
The Rotational Moment of Inertia Apparatus uses the three-string pendulum method. A plate hung on three strings oscillates about its vertical axis, and the moment of inertia of a rigid body placed on it is calculated from the measured torsional oscillation period.

How does the Rotational Moment of Inertia Apparatus measure the period?
The Rotational Moment of Inertia Apparatus measures the torsional oscillation period with a photoelectric sensor combined with a time counting device. Electronic timing avoids relying on a student's reaction speed with a hand stopwatch, which makes repeated readings more consistent.

Youngs Modulus Apparatus (Product Code: SLE/MCE/31) is a wire-extension apparatus used to find the relationship between the load on a wire and its resulting extension, and from it Young's modulus, in physics and engineering laboratories. Students read the extension on an engraved brass 0 to 30 mm scale with a movable vernier readable to 0.1 mm, while a ceiling clamp holds the wires from an overhead beam. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Youngs Modulus Apparatus Used For?

Two wires hang side by side from the ceiling clamp, one carrying the scale plate and the other the vernier. The tension weight keeps the wires taut, and as loading masses are added to the test wire its end moves down against the scale, so the vernier gives the extension directly to 0.1 mm. Because both wires share the same support and surroundings, sagging of the support or temperature drift affects both equally and largely cancels out.

Add masses in equal steps, wait a moment for each reading to settle, and take readings again while unloading to check the wire stayed elastic. Measure the wire diameter at several points and its length from the clamp, then plot load against extension; the slope gives Young's modulus. It is a staple of physics lab equipment in India for both school and first-year engineering practicals.

What to Specify When Ordering

• Number of sets for your practical groups
• Test wires (material and diameter) you would like quoted, as wires are not listed with the apparatus
• Slotted loading masses for the hooks — ask us to include them if needed
• A suitable overhead beam or door frame for fixing the ceiling clamp

OEM Manufacturer

This Youngs Modulus Apparatus is an OEM product of Jain Scientific Equipments Private Limited, better known by its trading name ScienceLab. The scale plate, vernier carrier and clamp are made at the company's own licensed factory at Saha, Ambala, Haryana, India, so schools, colleges, dealers and importers buy from the manufacturer rather than through a trader.

Vibration Of Spiral Spring Apparatus (Product Code: SLE/MCE/32) is a wall-mounted torsional oscillator used to study the stiffness and free vibration of a flat spiral spring in theory of machines and mechanical engineering laboratories. Its spring has a listed stiffness of 238 Nmm and a 10 x 1 mm cross-section, and two levers with sliding weights let students change the rotating mass while an integrated 360° scale reads the deflection. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Spiral Spring Vibration Apparatus Used For?

The practical runs in two stages. In the static stage, the metallic rod with its end masses applies a moment that turns the shaft against the spiral spring, and the angle scale shows the resulting deflection, so students can calculate the spring stiffness and read how far the spring was deflected initially. In the dynamic stage the rod is released, the spring-mass system oscillates freely, and the timed period is compared with the value predicted from stiffness and moment of inertia.

Sliding the weights along the two levers changes the moment of inertia without changing the spring, so one unit produces a full series of frequency readings for a graph. The ball-bearing axis keeps friction low, helping the oscillations last long enough to time several cycles. Fix the anodised aluminium plate firmly to a solid wall at a comfortable reading height; it is compact engineering lab equipment for vibration and SHM practicals in India and abroad.

What to Specify When Ordering

• Number of units, for example one per bench or student group
• Wall space for each 200 x 250 mm base plate
• A stopwatch or timer for the oscillation readings, if your laboratory does not already have one

OEM Manufacturer

ScienceLab is the OEM for this apparatus. Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, manufactures it at its own licensed factory at Saha, Ambala, Haryana, India, so it reaches buyers factory-direct rather than through a trading chain.

Technical colleges, TVET institutes, dealers and importers get quotations and technical answers from the source, and requests for replacement levers or weights on existing units go straight to the maker — just ask us. Read about the company on the ScienceLab profile page.

Bernoulli's Theorem Demonstration module (Product Code: SLE/MCE/33) is a hydraulics-bench module used to verify Bernoulli's equation by measuring pressure along a convergent–divergent duct in fluid mechanics laboratories. Its 8-tube manometer reads 0 to 300 mm of water from pressure taps along the conduit, and a Pitot tube probe travels along the duct to measure the head in each section. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Bernoulli's Theorem Demonstration Module Used For?

Students set the module on the hydraulics bench, level it with the adjustable legs and connect the inlet coupling to the bench supply. With water flowing, the manometer tubes show static pressure falling where the duct narrows and recovering as it widens, while traversing the Pitot tube shows how the head changes from section to section. The control valve at the outlet end lets them repeat the readings at several flow rates.

Timing the collection of water in the bench's volumetric measuring tank gives the flow rate, from which students calculate velocities at each section and compare measured pressure heads with those predicted by Bernoulli's equation. Swapping the removable conduit ends switches between convergent and divergent arrangements, so the same practical also explores pressure recovery and energy losses. It is a classic experiment in mechanics lab equipment sets for civil, mechanical and chemical engineering courses.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of the Bernoulli's Theorem Demonstration module. The module is fabricated and assembled at the company's own licensed factory in Saha, Ambala, Haryana, India, so universities, polytechnics, dealers and importers buy straight from the maker.

Dead Weight Pressure Gauge Calibrator (Product Code: SLE/MCE/34) is a portable deadweight tester used to calibrate pressure gauges, sensors and manometers by the direct p = F/A method in fluid mechanics and instrumentation laboratories. A capstan-operated hydraulic ram, balanced by weights acting on a piston of known area, generates pressures from 20 to 200 kN/m² with calibration accuracy better than 0.025% of reading. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Dead Weight Pressure Gauge Calibrator Used For?

The calibrator shows students the most direct definition of pressure: force divided by area. Masses placed on the piston set the target pressure, the capstan-operated ram raises the system pressure until the piston floats, and the flotation indicator on the top plate removes the guesswork about when that balance is reached. The gauge under test sees the same pressure, so its error can be recorded at each step.

Besides the Bourdon gauge fitted, other pressure sensors, manometers or Bourdon gauges can be connected and calibrated, which makes the unit useful both for teaching and for checking gauges used elsewhere in a laboratory. Level the instrument with the spirit level and adjustable feet before each session, and keep the oil system clean to protect the precision-machined piston and cylinder. For institutions building up test and measurement instruments, it supports fluid mechanics, instrumentation and metrology practicals.

Demonstration Pelton Turbine (Product Code: SLE/MCE/35) is an impulse-turbine test unit used to show how a water jet drives a Pelton wheel and to measure turbine torque, inlet pressure and speed in fluid mechanics laboratories. It delivers about 5 W at 500 min-1 (rpm) with approximately 30 L/min at a 2 m head, using a 14-blade wheel of 132 mm external diameter and a 10 mm jet. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Demonstration Pelton Turbine Used For?

In a Pelton turbine the pressure energy of the water is converted into kinetic energy entirely in the distributor: the jet is accelerated in a nozzle and directed tangentially onto the blades of the wheel. Each blade turns the jet back through roughly 180°, transferring the jet's impulse to the wheel — a clear, visible example of the impulse principle that students can contrast with reaction turbines.

During a test, students tighten the band brake in steps, read the spring balances to find the braking force and hence torque, note the inlet pressure on the manometer and measure rotational speed with a non-contact speed sensor. From these readings they plot torque and output power against speed to locate the turbine's most effective operating point. It is a valuable addition to mechanics lab equipment for mechanical and civil engineering hydraulics courses.

What to Specify When Ordering

• Number of units required for your laboratory
• Whether a non-contact speed sensor, needed for rotational-speed measurement, should be included in the quotation
• How water will be supplied to meet the stated operating point of approx. 30 L/min at H = 2 m
• Available space and handling for a 1000 x 800 x 1200 mm unit weighing 90 kg
