As shown, the truss is loaded by the forces P1 = 208lb and P2 = 398lb and has the dimension a = 4.00ft .
Using the method of joints, determine FAB, FBC, and FBD, the magnitude of the force in each of the members connected to joint B. Assume for your calculations that each member is in tension, and include in your response the sign of each force that you obtain by applying this assumption. Express your answers numerically in pounds to three significant figures separated by commas.
