To understand the relationship between moments of force, the amount of force and the length of the lever arm. Includes a meter stick, three knife-edge clamps, an aluminum support, two mass hangers, slotted masses from 1 gm to 500 gm and a storage rack.

To demonstrate levers, movements and the principles of mass measurement. Comprises a ½ meter stick, a clamp, a stand, two weight hangers and masses.

The heavy duty rotating platform illustrates the concept of rotational inertia. The platform can easily withstand weight of 80 kg. Solid, heavy metal legs and grooved platform ensures maximum stability.

Gyroscope with Gimbal Cradle is an excellent, inexpensive apparatus, which is used to explore the mysteries of the precession, inertial guidance, gyroscopic compasses and stabilization. It is precision machined and balanced and runs smoothly with little vibration. Provided with pull string with handle, weight set and support hook. A pendulum mounting is also supplied that can be used for investigating the rolling moment. It demonstrates the principle of angular momentum. Supplied with user manual.

A simple and economical apparatus for demonstration of geometrical center of gravity of two-dimensional objects. PVC rod mounted on a base with a suspension screw at the top, 4 clear acrylic laminas – circular, triangular, square and trapezoidal. Each lamina has suspension holes along its periphery. The point of intersection of lines drawn from the point of suspension of 2 or more holes of a lamina gives the center of gravity of that lamina.
