WebDec 21, 2009 · Problem 3-9 A tapered bar AB of solid circular cross section is twisted by torques T 36,000 lb-in. (see figure). The diameter of the bar varies linearly from dA at the left-hand end to dB at the right-hand end. The bar has length L 4 ft and is made of an aluminum alloy having shear modulus of elasticity G 3 106 psi. The allowable shear stress in the bar … WebUntil now, our approach has been: 1. determine the external forces from a statics analysis, 2. calculate the internal stress, and 3. use Hooke’s law to determine the strain. For instance, take the structure below and determine the stress at its center. You are given the applied force and the cross sectional area, and this becomes a simple ...
