Rigid bar ABC is subjected to a concentrated load P, as shown in Figure P4.15. Inclined member (1) has a cross-sectional area of A₁
= 2.250 in.2 and is connected at ends B and D by 1.00-in.- diameter pins in double shear connections. The rigid bar is supported at C by a 1.00-in.-diameter pin in a single shear connection. The yield strength of inclined member (1) is 36 ksi, and the ultimate strength of each pin is 60 ksi. For inclined member (1), the minimum factor of safety with respect to the yield strength is FS_min
= 1.5. For the pin connections, the minimum factor of safety with respect to the ultimate strength is FS_min
= 2.0. Determine the maximum load P that can be supported by the structure.
