required thickness of member BC and the diameter of the pins at A and B if the allowable normal stress for member BC sallow = 29ksi is and the allowable shear stress for the pins is

FBD 3. Determine the required thickness of member BC and the diameter of the pins at A and B if the failure normal stress for member BC is Ofail = 30 ksi, and the failure shear stress for the pins is Tfail = 12 ksi. Use a safety factor of 1.2 to your design. Solution: 1.5 in. 60° 8 ft 5 kip/ft
