A woman applies a torque to a nut with a wrench 0.250 m long. Because of the cramped space, she must exert a force upward at an angle of 70.0° with respect to a line from the nut through the end of the wrench. If the force she exerts has magnitude 46.0 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.)
a 1,460-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1,584-N crate hangs from the far end of the beam.

The large quadriceps muscle in the upper leg terminates at its lower end in a tendon attached to the upper end of the tibia (see Figure a). The forces on the lower leg when the leg is extended are modeled as in Figure b, where T is the force of tension in the tendon, w is the force of gravity acting on the lower leg, and F is the force of gravity acting on the foot. Find T when the tendon is at an angle of 25.0° with the tibia, assuming that w = 29.0 N, F = 12.3 N, and the leg is extended at an angle ? of 40.0° with the vertical. Assume that the center of gravity of the lower leg is at its center and that the tendon attaches to the lower leg at a point one-fifth of the way down the leg. (Give the magnitude.)
