A pulley is supported by a circular pin at A. The pin has a diameter of d = 0.375 in., and each side of the pulley support bracket has a thickness of t = 0.1875 in. The average shear stress in the pin cannot exceed 45 ksi, and the bearing stress in the pulley support bracket cannot exceed 60 ksi. Determine the maximum value of Pmax that can be supported by the assembly.
