The pin-connectsed structure consists of a rigid bar ABCD and two bronze alloy [E = 100 GPa] bares, each with a cross-sectional area of 340 mm2. bar (1) has a length L1 = 810 mm and bar (2) has a lenght L2 = 1080 mm. Assume dimensions of a = 480mm, b = 38mm, and c = 600mm. If the allowable normal stress in bars (1) and (2) must be limmited to 165 MPa each, determine: a) the maximum load P that may be applied at D to the rigid bar.                                                                               b) The deflection at D for the load determined in part (a).

Question

The pin-connectsed structure consists of a rigid bar ABCD and two bronze alloy [E = 100 GPa] bares, each with a cross-sectional area of 340 mm2. bar (1) has a length L1 = 810 mm and bar (2) has a lenght L2 = 1080 mm. Assume dimensions of a = 480mm, b = 38mm, and c = 600mm. If the allowable normal stress in bars (1) and (2) must be limmited to 165 MPa each, determine:

a) the maximum load P that may be applied at D to the rigid bar.                                                                               b) The deflection at D for the load determined in part (a).
