2. A solid circular shaft has a diameter of 2 in. The shaft, in its current geometry, does not have an ideal robustness against the operational torsional loading. Adding extra material to the shaft is not option due limited resources. It has been suggested that an increase in the shaft's polar moment of inertia will improve its mechanical propertie Can you suggest a process that will result in threefold increase in the polar moment of inertia without changing the shaft section area? What are the new dimensions?

When selecting for a cheap, stiff shaft (i.e. in torsion) the constraint equations for the magnitude of twist use the shear modulus (G) rather than Young's modulus (E). Why can we reasonably substitute E (which is more readily available) for G in the material index? O Generally, E is proportional to G so ranking with one of them results in the same ranking order as with the other. O So long as the radius of the shaft is free, and so can compensate for the change in modulus, the constraint will be fulfilled either way. OG is smaller than E so fulfilling the constraint for G means we automatically fulfil the constraint using E. O The value for E and G are actually quite similar and the error introduced is small compared to the assumptions we are making.
