A long cylindrical rod of diameter 200 mm with thermal conductivity of 0.5 W/m. K experiences uniform volumetric heat generation of 24,000 W/m3 . The rod is encapsulated by a circular sleeve having an outer diameter of 400 mm and a thermal conductivity of 4 W/m. K. The outer surface of the sleeve is exposed to cross flow of air at 37OC with a convection coefficient of 25 W/m2 .K. (a) Find the temperature at the interface between the rod and sleeve and on the outer surface. (15 points) (b) What is the temperature at the center of the rod

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
