Problem 9.003 A rigid steel bar is supported by three rods, as shown in the figure. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rods (1) is 450 μm/m. Assume initial rod lengths of L1-2250 mm and L2-1700 mm. Determine (a) the normal strain in rod (2) (b) the normal strain in rod (2) if there is a 1-mm gap in the connections between the rigid...
P2.006 (Multistep) The rigid bar ABC is supported by three bars as shown in the figure. Bars (1) attached at A and C are identical, each having a length of Li158 in. Bar (2) has a length of L2-96 in.; however, there is a clearance of c 0.26 in. between bar (2) and the pin in the rigid bar at B. There is no strain in the bars before the load P is applied, and a 59 in. After application...
The rigid bar AC is supported by two axial bars (1) and (2). Both axial bars are made of bronze [E = 100 GPa; a = 18 x 10-6 mm/mm/°C). The cross-sectional area of bar (1) is A1 = 226 mm- and the cross-sectional area of bar (2) is Az = 362 mm. After load P has been applied and the temperature of the entire assembly has increased by 22°C, the total strain in bar (2) is measured as 1020...

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. \(E_{\text {st }}-200 \mathrm{GPa}, E_{\text {al }}-70 \mathrm{GPa}\).
The rigid bar AB is pinned at A and supported by two aluminum rods (E = 10 x 103ksi) with diameter d = 1.2 in and the length shown for each on the figure. If the rigid bar is initially vertical, determine (a) the reaction exerted at A and (b) the average normal stress in each rod when the 40-kip force is applied. 40 kip B 2 ft d=12 in ELIF 2 ft- (a) reaction at A 3 ft d=1.2...
