About This Product
The kit is used to teach static equilibrium, coplanar forces, centre of gravity, torque and the law of moments. Students balance unequal masses on the lever bar to check that the moments on each side are equal, then compare theoretical and actual mechanical advantage using a block-and-tackle pulley system and a spring dynamometer.
