The jib crane is pinned at A and supports a chain hoist that can travel along the bottom flange of the beam, 1 ft ≤ x ≤ 12 ft. If the hoist is rated to support a maximum of 1500 lb, determine the maximum average normal stress in the in.-diameter tie rod BC and the maximum average shear stress in the -in.-diameter pin at B.
