Draw FBDs as required Clearly state all assumptions made towards solving the problem 1) In the structure shown, 큭in dia. pin is used at A and jin dia, pins are used at B and D If the thickness of member BD is ^in, the ultimate shearing stress for the pins at A, B&D are 5ksi and the ultimate normal stress for the link BD is 8ksi and the overall factor of safety of 3 is desired. Determine the allowable horizontal...
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...
1.52 Solve Prob. 1.51, assuming that the structure has been redesigned to use 16-in.-diameter pins at A and C as well as at B and that no other changes have been made. A in. 8 in. B C 4 in. 6 in. Fig.P1.51 1.51 Link AC is made of a steel with a 65-ksi ultimate normal stress and has a 2-in. uniform rectangular cross section. It is connected to a support at A and to member BCD at C by-in.-diameter...
