Starting with a 2inch diameter rod of brass we would like to

Starting with a 2-inch diameter rod of brass, we would like to process 0.2-inch diameter rods that possess minimum yield strength of 40 ksi and a minimum elongation to fracture of 40%, (see the following figure). Design a process that achieves that.

Solution

Cold extrusion can be done to achieve the no.of rods with required diameter.

Due to cold working strength will increase
