Question

the connected bar BC is used to increased the lever arm of the crescent wrench as shown. If a clockwise moment of Ma=120N*m is needed to tighten the nut at A and the extension d=300mm, determine the requiered force F in order to develop this moment.

extension d = 300 mm, determine the required force F order to develop this moment. the connected bar BC is used to increased the lever arm of the crescent wrench as shown.

Explanation / Answer

F = Ma * dcosq = 120 * 300cos30' just calculate
