A suitable standard bright steel bar shaft diameter if the limiting
shear stress is 80 MPa.
For the specific application, the weight of the mechanism is an
important consideration, and applications elsewhere proved that it
would be safe to increase the limiting shear stress to 90 MPa. It was
therefore decided to replace the solid shaft with a hollow shaft.
Space limitations, however, prevent a larger diameter shaft.
Determine the internal diameter of the hollow shaft. Also determine
the percentage weight saving on the shaft.
