A uniform board 12 ft long weighs 10 lbs. Two feet from the left is centered a 3 lbs. structure. How far from the left end is the balance point i.e. the point at which if you applied 13 lbs. upward force would balance the board and structure??

    total weight = 10 + 3 = 13
    13 x = 6(10) + 3(2) = 66
    x = 66/13 = 5.08 ft
