A wire made from Material Y has a 3 millimeter [mm] diameter and is 1.25 feet [ft] long. A stress is created by applying a force over the circular cross-sectional area of the wire, where the circular area is given by: A = π r2. This stress causes a strain of 0.045 [mmmm]. Determine the force used to stretch the wire, in units of newtons [N].

Question

A wire made from Material Y has a 3 millimeter [mm] diameter and is 1.25 feet [ft] long.

A stress is created by applying a force over the circular cross-sectional area of the wire, where the circular area is given by:  A = π r2.

This stress causes a strain of 0.045 [mmmm].

Determine the force used to stretch the wire, in units of newtons [N].
