A man applies a torque to a nut with a wrench 0.450 m long. Because of the cramped space, he 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 he exerts has magnitude 52.0 N, what magnitude torque (in N · m) does he apply to the nut? (Assume that the force is applied at the end of the wrench.)

To study torque experimentally, you apply a force to a beam. One end of the beam is attached to a pivot that allows the beam to rotate freely. The pivot is taken as the origin or your coordinate system. You apply a force of F = Fx i + Fy j + Fz k at a point r = rx i + ry j + rz k on the beam. Part (a) Enter a vector expression for the resulting torque, in terms of the unit vectors i, j, k and the components of F and r. Part (b) Calculate the magnitude of the torque, in newton meters, when the components of the position and force vectors have the values rx = 4.42 m, ry = 0.015 m, rz = 0.035 m, Fx = -4.2 N, Fy = 6.6 N, Fz = 2.8 N. Part (c) If the moment of inertia of the beam with respect to the pivot is I = 368 kg˙m2, calculate the magnitude of the angular acceleration of the beam about the pivot, in radians per second squared.
