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

The 7-mm-thick base plate of an iron is made of an aluminum alloy (? = 2,700 kgm-3; c = 950 Jkg-1K-1; k = 200 Wm-1K-1; ? = 0.8), and has outer surface area of 0.04 m2, perimeter of 0.7 m, and maximum length of 0.3 m. An electrical resistance heater applies a uniform heat flux of 12.5 kWm-2 to the inner surface of the base plate when the iron is turned on. The outer surface of the base plate is...

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...
