Member AB in Figure P5.74 is a quadrant of a circle lying in the (x, z) plane, has a circular cross section of radius r, which is small compared with R, and is supported by a spring (spring constant k) at B, whose action line is parallel to the y axis. Determine the force in the spring when torque T0is applied at B with action line parallel to the negative z axis.
