1) An airplane's weight change is determined by reading the strain gauge A mounted on the plane's aluminum wheel strut. Before the plane is loaded, the strain gauge reading in the strut is &₁ = 0.00100 in./in., whereas after loading &2 = 0.00243 in./in. Determine the change in the force on the strut if the cross-sectional area of the strut is 3.5 in². and E = 10(10³) Ksi. O
