The bottom of the hollow shaft shown in figure 2 is fixed to a surface acting as a rigid support. Suppose the hollow shaft has an inner radius of r, = 40mm and outer radiusr, = 55mm Figure 2 a) Determine the torque T if the maximum shearing stress is not to exceed 60 MPa. b) Suppose that the shaft is solid instead, with the same outer radius. Use the calculated torque T from part a, and determine the maximum shearing stress of the solid shaft due to torque c) Why would we still choose a hollow shaft when it will experience higher stress compared to a solid shaft?

a) Determine the torque T if the maximum shearing stress is not to exceed 60 MPa.
b) Suppose that the shaft is solid instead, with the same outer radius. Use the calculated torque T from part
a, and determine the maximum shearing stress of the solid shaft due to torque T.
c) Why would we still choose a hollow shaft when it will experience higher stress compared to a solid
shaft?
