The sanding-drum mandrel shown in the figure is made for use with a hand drill. The mandrel is made from a rubber-like material that expands when the nut is tightened to secure the sanding sleeve placed over the outside surface. If the diameter D of the mandrel increases from 1.60 in. to 1.73 in. as the nut is tightened, determine (a) the average normal strain along a diameter of the mandrel. (b) the circumferential strain at the outside surface of the mandrel. Sanding sleeve - Mandrel Answers: (a) ED= in./in. (b) Ec= in./in.
