A 32 N weight and an 18 N weight hang from the ends of a string placed over a pulley. The 32 N weight is initially lifted up so that when the system is released it will fall down while the 18 N weight moves up. Assume the pulley is frictionless and that the pulley and string are massless. Find the tension in the string.

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?
