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
(a) The allowable force P that can be applied
(b) Explain, with a logical reason, why the allowable value is a maximum/minimum?

2) The beam shown is supported by steel member BC as shown. Due to the forked ends on the member, consider the supports at B and C to act as pins for x-x axis buckling and as fixed supports for y-y axis buckling. Member BC is made of A992 steel with a modulus of elasticity of 29,000 ksi and a yield strength of 50 ksi. a) Calculate the maximum allowable load, P, on the system (in kips) considering buckling and...
