An Aluminum alloy billet with Diameter of 232mm and Length of 634mm is to be extruded at temperature much below the recrystallization temperature to a tube of and outer diameter of of 50mm and inner diameter 38mm. If the ram speed is 65mm/s and the materials constants are K=287MPa, n=0.3, C=142MPa and m = 0.2, then find the strain resulting from this extrusion process

A steel and aluminum wire, each of length L and diameter d, are joined to make a single wire of length 2L and diameter d. The wire is attached to fixed supports so that it is straight but with negligible tension. After being cooled by a change in T, the aluminum is found to have increased in length by 0.0140% (and the steel decreased in length by the same percentage.) If d = 1.00 mm, find: (a) the difference in...

Kerosene enters a 5 cm diameter tube at 35C with a velocity of 3 m/s. The tube is wrapped with a resistance heating element so that when it is energized a uniform heat flux is imposed on the tube. At the exit of the tube, the temperature of the kerosene is to be 45C. A constraint is placed on the process, such that the local kerosene temperature cannot exceed 80C; this is likely to occur at the wall of the...
