The cable from B to A (the sailboat’s forestay) exerts a 230-N force at B. The cable from B to C (the backstay) exerts a 660-N force at B. The bottom of the sailboat’s mast is located at x = 4 m, y =0. What is the sum of the moments about the bottom of the mast due to the forces exerted at B by the forestay and backstay?
