Question

A horizontal meter stick with a scale that increases from left to right has a clamp at the 0.370 m mark (the 37.0 cm mark) from which a mass hanger with a weight is hung. The clamp has a mass of 15.00 g,the mass hanger is marked 50 g and the weight has a mass of 38.00 g. The entire system is static; it is in rotational equilibrium. Remember that, in such a situation, any point can be thought of as the pivot point with torques being calculated about it.

a) What torque (in N*M) does the weight at the 0.37 m mark produce about the 0.00 m mark? Make sure the sign is correct.

Explanation / Answer

M = r ( 15 + 50 + 38 ) e-3 * 9.8

M = 0.37 ( 15 + 50 + 38 ) e-3 * 9.8

M = 0.373 N . m <------ans
