B. Moment Of Force Apparatus
This apparatus shows the relationship between moment of force, the amount of force and the length of the lever arm. By simply adjusting weights fitted on a meter stick lever to establish equilibrium, students will observe the law of torque for various centres of rotation, compare clockwise and counter-clockwise torques, measure various lever arms, and calculate torque. Consists a meter stick, three knife edge clamps and an aluminium support. Supplied with 100g & 200g hooked weight.
CP00050877 Pulley Blocks
Incorporating 50mm diameter plastic pulleys carried in tough plastic frames. The blocks are available in single, double and triple sheave form with plain bearing pulleys. The bearing pin may be rapidly removed from the frame, thus releasing the pulley(s) and allowing easy ‘stringing up’. A simple locking system prevents the pin accidentally coming out. All blocks have a hook at each end. Overall length of frames: 70mm.
