A tie-down on the deck of a sailboat consists of a bent bar bolted at both ends, as shown in the figure. The diameter dg of the bar is 1/4 in., the diameter dw of the washers is 7/8 in., and the thickness t of the fiberglass deck is 3/8 in. If the allowable shear stress in the fiberglass is 300 psi, and the allowable bearing pressure between the washer and the fiberglass is 550 psi, what is the allowable load Pallow on the tie-down?
