29. A worker applies a torque to a nut with a wrench 0.500 m long. Because of the cramped space, she must exert a force upward at an angle of 60.0° with respect to a line from the nut through the end of the wrench. If the force she exerts has a magnitude of 80.0 N, what magnitude torque, in N.m, does she apply to the nut?

27. A meter stick is found to balance at the 49.7-cm mark when placed on a fulcrum. When a 50.0-gram mass is attached to the 10.0-cm mark, the fulcrum must be moved to the 39.2 cm mark for balance. What is the mass, in grams, of the meter stick? Answer: 139
