For the following problem, assume the modulus of elasticity for steel to be 30,000,000 psi (207 000) and the proportional limit to be 34,000 psi (234 MPa). Refer to Appendices F or G for other materials.
A titanium alloy bar elongates 0.500 in. when subjected to an axial tensile load of 100 k. The bar is 16 ft long and has a cross-sectional area of 2.25 in2. Compute the modulus of elasticity E. Use a proportional limit of 125 ksi.
