Member BCD is supported in the position shown using the 1/2 ×
1/4 in2 rod AC and 1/4 in diameter pins at B, C&D. The ultimate
bearing stress for the pin at B is 5ksi, the ultimate shear stress
for the pin at B is 7 ksi and the ultimate normal stress for the
link AC is 12ksi. Assuming that the pins at A and C are strong and
a factor of safety of 3 is desired, determine
