1) A 35 mm diameter shaft operating at 2000 rpm transmits 1000 kW. The bending and axial loads on the shaft are negligible. a. What is the shear stress on the surface of the shaft? b. You are considering using a hollow shaft with an inside diameter 0.8 times the outside diameter. What outside diameter would be required to give the same outer surface stress? c. How do the weights of the solid and hollow shafts compare?
