A 30-lb weight is attached to one end of a 6-ft uniform beam whose own weight is 20-lb. Where is the balance point? Thanks in advance.

  • Physics -

    take moments around end where 30 lb weight is
    total force up = 20+30 = 50

    50 x = 20 * 3

    x = 6/5 = 1.2 ft from end where 30 lb weight is
