A square steel tube of length L = 6 m with an outer width of 250mm and the inner dimension is 210 mm. The tube hangs from a pin of diameter "d" that is held by the cables at points A and B.
Weight density of steel = 77 kN/m3.
Allowable stresses:
Shear stress in the pin = 60 MPa
Bearing stress between the pin and the tube = 90 MPa
A. Determine the tensile force in the cable.
B. Determine the diameter of pin based upon shear.
C. Determine the diameter of pin based upon bearing.
