D. The tube BC is safe against both yielding and buckling
h) Pin C has a diameter of 30 mm; calculate the shear stress τ of the pin C, when considering one cross-section for shear stress calculation:
Transcribed Image Text:In the system shown in Figure 1, bar AB and tube BC are pin-jointed at A, B and C. Tube BC is made of steel with Young's modulus E = 200 GPa and yield stress oy = 340 MPa. It has a
symmetric cross section, as shown in Figure 1. Bar AB is subjected to a uniformly distributed load of 10 kN/m. A pull load is applied at joint B through a wheel, as shown in the figure.
The friction coefficient between the wheel and the rope is 0.5.
