Forces Table

For demonstrating the law of composition and resolution of forces. The 400mm diameter, thick, machined aluminium tabletop has a laser engraved rim with graduations for accurate and easy-to-read measurements and is mounted on a vertical support rod with levelling screws in the feet. Cords are fastened to the peg in the centre and can be passed over up to four pulleys.
The pulley clamps are specially designed to conform to the curve of the circular table so the pulleys won't wobble. Low inertia pulleys with miniature bearings provide negligible friction, and a central fiducial mark ensure parallax-free angle readings.
Set includes four pulleys, four mass hangers of 100g each, and an additional sixteen weights (4 x 10g, 4 x 20g, 4 x 50g and 4 x 100g).
Masses are made of steel and chrome plated.
