155 lb and is 3.00 ft from one end. The other washer is 4.00 ft from the other end. If the force supported by the end near the first washer is 200 {line above last zero}, how much does the second washer weigh?
Let the two upward forces be F1 and F2. F1 + F2 = 155 + 75 + X. Taking moment about the end near the washer of X lb 4X + 6*75 + 12* 155 = 12.*200 X = 22.5 lb ==================================
