Unformatted text preview: B relative to A can be found using equation 4.8. This stress is uniform across the rod and has the same value at any cross section along the longitudinal axis except close to the ends where the load is applied. yy 5659 psi = yy P A = 2. (a) The loading is simple axial tension so all components of the stress tensor are zero except σ yy , which is found using equation 4.7. A 1.767 in 2 = A π d 2 ⋅ 4 = 1. Calculate the cross-section area of the rod. Solution: See Mathcad file P0455. L AB 8 in ⋅ = L A 12 in ⋅ = L 30 in ⋅ = Lengths E 30 10 6 ⋅ psi ⋅ = Modulus of elasticity d 1.50 in ⋅ = Diameter Given: Tensile load P 10000 lbf ⋅ =...
