Fly Wheel
Product Code : LSK-AM-11089
Fly Wheel (SKU LSK-AM-11089) is a wall-mounted flywheel for measuring the moment of inertia of a wheel about its axle. A mass on a cord wound round the shaft falls and spins the wheel, and the revolutions and times give the result. It serves Class 11 extension work and B.Sc. and engineering mechanics practicals. As a science apparatus manufacturer in India, Science Lab Supplies makes it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and supplies schools, colleges, tender contractors and distributors directly.
Specifications
The flywheel is a carefully machined and balanced cast iron wheel on a steel spindle running in ball bearings held in strong iron brackets. Its sides are smoothly painted and its chrome-plated rim carries a thick reference line read against a pointer on one bracket. Wheel diameters of 15, 20 and 25 cm are listed.

Applications and Experiments for the Fly Wheel
The flywheel is used to find its moment of inertia about the axis of rotation, and to account for friction at the bearings, by timing a falling mass and counting revolutions after the cord detaches. It is a routine experiment in B.Sc. physics and engineering mechanics lab equipment in India.
- B.Sc. physics: moment of inertia of a flywheel.
- B.Tech and diploma mechanics: energy transfer from a falling mass to rotation.
- Class 11 physics: demonstrating rotational kinetic energy and torque.
Standard Scope of Supply
Each Fly Wheel is supplied with its steel spindle, ball-bearing iron brackets, pointer, wall-fixing base, cord and hook, in the wheel diameter you choose. The model with a revolution counter is quoted on request. Masses to hang on the hook are not listed with the set.
Packing, MOQ and Lead Time
Request a quotation for one flywheel or for several in the same or different wheel sizes. Our quotation lists packing, delivery time and price for the quantity specified, and slotted masses or other rotational mechanics apparatus can be added to it.
Science Lab Supplies has an Importer-Exporter Code and is therefore able to ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. Use the enquiry cart to collect items, the contact page to ask a question, or the lab tender page for tender supply.
Frequently Asked Questions
Which wheel sizes does the Fly Wheel come in?
Three wheel diameters are listed: 15 cm, 20 cm and 25 cm. A model with a revolution counter is also available; specify the size and version when you enquire.
How is the flywheel mounted?
The base has four holes so the apparatus can be fixed to a wall. The wheel then turns on its steel spindle in ball bearings held by iron brackets.
How are revolutions counted?
The chrome-plated rim carries a thick line that passes a pointer on one bracket, so each turn can be counted by eye. The version with a revolution counter records turns for you.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The flywheel is produced at the Science Lab Supplies factory in Saha, Ambala, India, and the quotation you receive is issued by that factory.
