A worker applies a torque to a nut with a wrench 0.200 m long. Because of the cramped space, she must exert a force upward at an angle of 50.0° with respect to a line from the nut through the end of the wrench. If the force she exerts has a magnitude of 70.0 N, what magnitude torque (in N · m) does she apply to the nut? (Assume that the force is applied at the end of the wrench.)
