The cable has tensile force T and is attached at C. The length of the pole is 6.0 m, the outer diameter is d = 140 mm, and the wall thickness t = 12 mm. The pole pivots about a pin at A. The allowable shear stress in the pin is 60 MPa and the allowable bearing stress is 90 MPa. The diameter of the cable is 8 mm. 1. Find the minimum diameter (mm) of the pin at A to support the weight of the pole in the position shown. A. 2 C. 4 B. 3 D. 5 2. Calculate the elongation (mm) of the cable CD. A. 0.889 C. 1.286 B. 0.961 D. 1.186 3. Calculate the vertical displacement of point C, in mm. A. 1.337 C. 2.315 B. 1.186 D. 2.864 Thanks for watching!
