Problem 1 A composité beam made of concrete (c) and six steel Steel bars (s) bars is shown below. The steel bars run through the concrete from the top to bottom and have the same length as the concrete block. Each steel bar has a diameter of in. Calculate the cross- sectional area of the concrete and the area of all the steel bars. If the temperature rises by AT 65 °F, determine the normal stress in the steel bars....
The rigid beam in (Figure 1) is supported by the three suspender bars. Bars AB and EF are made of aluminum and bar CD is made of steel.
The rigid beam in (Figure 1) is supported by the three suspender bars. Bars AB and EF are made of aluminum and bar CD is made of steel. Part A If each bar has a cross-sectional area of \(480 \mathrm{~mm}^{2}\), determine the maximum value of \(P\) if the allowable stress is \(\left(\sigma_{\text {allow }}\right)_{\text {st }}-190 \mathrm{MPa}\) far the steel and \(\left(\sigma_{\text {allow }}\right)_{\text {al }}-150 \mathrm{MPa}\) for the aluminum. \(E_{\text {st }}-200 \mathrm{GPa}, E_{\text {al }}-70 \mathrm{GPa}\).
