Question

A horizontal load P is applied to an assembly consisting of two inclined bars, as shown in the figure.  The cross-sectional area of bar (1) is 1.30 in.2, and the cross-sectional area of bar (2) is 1.75 in.2.  The normal stress in either bar may not exceed 24 ksi.  Determine the maximum load P that may be applied to this assembly.  Assume dimensions of a=14.5 ft, b=9.0 ft, and c=14.5 ft. 

Find the ratio, (F1/F2), where F1 is the force in member (1) and F2 is the force in member (2).  Both bars are in tension, so these forces are both positive according to the sign conventions.

A horizontal load P is applied to an assembly consisting of two
inclined bars, as shown in the figure. The cross-sectional area of bar
(1) is 1.30 in.?, and the cross-sectional area of bar (2) is 1.75 in.?. The
normal stress in either bar may not exceed 24 ksi. Determine the
maximum load P that may be applied to this assembly. Assume
dimensions of a = 14.5 ft, b = 9.0 ft, and c = 14.5 ft.
