A cylindrical drum of length l and radius r can rotate inside a fixed concentric cylindrical casing, the clearance space c between the drum and the casing being very small and filled with liquid of dynamic viscosity µ. To rotate the drum with angular velocity o requires the same power as to pump the liquid axially through the clearance space while the drum is stationary, and the pressure difference between the ends of the drum is p. The motion in both cases is laminar. Neglecting end effects, show that 2µlro/3 p = c2

Civil engineering question (Strength of material) - The 30 foot long cantilevered beam is depicted in the illustration. 6 inches thick and 2 feet deep. It is constructed of steel with a 15.2 slug/ft bulk density. At a 30 degree inclination to the vertical in the x-y plane, it can hold a 1000 lbf load. Between 250 °F at the support to 70 °F at its free end, the temperature of the beam changes linearly. Calculate its weight and mass, and convert the measurements to SI units.
