A: What interference fit is required in order to transmit 100 kW at 70 RPM between a (250mm outer diameter and
150mm inner diameter) steel shaft and a 350 mm outside diameter cast iron hub which is 200 mm long. Also state
the maximum actual tangential stresses at the various surfaces. (Take Young's modulus for the steel and cast iron
to be 200 and 100GPA, respectively, assume the coefficient of friction is 0.12 and that Poisson's ratio is 0.3 for
both materials.)
