Question

Determine the values of the stress in portions AC and CB of the steel bar shown (Fig.) when the temperature of the bar is -500 F, knowing that a close fit exists at both of the rigid supports when the temperature is +750 F. Use the values of E = 29 * 106 psi and ?= 6.5*10- 6 / 0 F for steel. Assume that the effect of stress concentrations due to the change in crosssection at point C can be neglected.

Step 1

5 \times 10^{-6} /^\circ F \) - The bar is fixed at both ends (rigid supports), so no net elongation is possible. - The bar consists of two portions: AC and CB, with different cross-sectional areas (not given explicitly here, but assumed known from the figure). - Show more…
