A steel has a modulus of elasticity of 29,000 ksi and an elastic limit of 52 210 psi. A rod of this material and cross section of 0.0186 in2 and 36 in length is fastened vertically to a beam with a load of 410 lb at the opposite end. Determine: a) If this load is removed, will the bar return to its initial length? Justify the answer; b) The unitary deformation of the bar in these conditions; c) The minimum...
