A cable is wound around the hub of a spool that has a mass of 50 kg and center of gravity at G, and is connected to a block with a mass of 30 kg. It is known that the coefficients of static friction are 0.15 under the spool and 0.2 under the block. Compute the maximum counterclockwise moment of a couple that can be applied without disturbing the equilibrium of the system.

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
