A 3105 aluminum wire is to be drawn to give a 1-mm-diameter wire having a yield strength of 20,000 psi. Note 3105 designates a particular aluminum alloy.

(a) Find the original diameter of the wire;

(b) calculate the draw force required; and

(c) determine whether the as-drawn wire will break during the process. (See Figure.)
