Wires B and C are attached to a support at the left-hand end and to a pin-supported rigid bar at the right-hand end (see figure). Each wire has cross-sectional area A =0.03 in2 and modulus of elasticity E = 30 X 106 psi. When the bar is in a vertical position, the length of each wire is L = 80 in. However, before being attached to the bar, the length of wire B was 79.98 in. and wire C was 79.95 in. Find the tensile forces TBand Tc in the wires under the action of a force P = 700 lb acting at the upper end of the bar.
Two cables, each having a length i. of approximately 40 m, support a loaded -container of weight W (see figure). The cables, which have an effective cross-sectional area A = 48.0 mm2 and effective modulus of elasticity E = 160 GPa. are identical except that one cable is longer than the other when they are hanging separately and unloaded. The difference in lengths is d = 100 mm. The cables are made of steel having an elastoplastic stress-strain diagram with a r= 500 MPa. Assume that the weight ft' is initially zero and is slowly increased by the addition of material to the container. (a) Determine the weight Wythat lirsl produces yielding of the shorter cable. Also, determine the corresponding elongation 5 of the shorter cable. (b) Determine the weight Wpthat produces yielding of both cables.

The pin connected structure shown in the figure consists if a triangle shaped rigid bar, a cast iron bar(1) and an alluminum alloy rod(2). Bar (1) has a rectangular cross sectional area (width x thickness) of A1 = 50 * 25 mm2 and comes with material properties of E1 = 168 GPa and a1 = 10.8 * 10-6 /C . The diameter of rod (2) is d2 = 40 mm and it comes with material properties of E2 = 69 GPa and a2 = 23.6 * 10-6 /C. Both members are unstressed when the structure is assembled at 25 C.
