Extracted text: 1. A 150 inch long aluminum bar is subjected to a tensile stress of 25000 psi. Find the elongation. (E = 10 x 106 psi) 2. A steel specimen is subjected to a tensile force of 400 kips. If the Poisson's Ratio is 0.20, and the modulus of elasticity is 2.8 x 107 psi. Find the dilatation (e). e = €x + €y + €z (Dilatation – is the sum of the strain in all three coordinate directions.)
