A steel wire of length 1.40 m and diameter 1.00 mm is joined to an aluminum wire of identical dimensions to make a
composite wire of length 2.80 m.
What is the resulting change in length AL of this
composite wire if an object with a mass of 5.00 kg is hung
vertically from one of its ends? (Neglect any effect the
masses of two wires have on the changes in their lengths.)

2. In engineering, the modulus of elasticity Is a way to measure how much
an object deforms along an axis when opposing forces are applied
among that axis. The formula can be expressed as E =
ddsof elasticity, F is the axial force, & is a cdeformation measure,
L s the original length of the object, and A is the croSs-sectional area.

Part A: Rearrange the elasticity formula to find the cross-sectional area, A
Part B: Rearrange the elasticity formula to find the original length, Lo, of
the object.
