solution

The solid rod shown is fixed to a wall, and a torque T = 75 N - mis applied to the end of the rod. The diameter of the rod is 26 mm__ When the rod is circular, radial lines remain straight and sections perpendicular to the axis do not warp. In this case, the strains vary linearly along radial lines. Within the proportional limit, the stress also varies linearly along radial lines. If point A is located 4 mum from the center of the rod, what is the magnitude of the shear stress at that point? Express your answer to three significant figures with the appropriate units.
