Balancing problem

  1. Nov 11, 2006 #1
    A 67-kg adult sits at one end of a 10-m board, on the other end of which sits his 23-kg child. Where should the pivot point be placed so the board (ignore its mass) is balanced?

    67d=(10-d)23
    67d=230-23d
    90d=230
    d=2.56 m

    The fulcrum should be at 2.56 m

    Have I set this up right

    Looks okay to me, although you should state where your distance d is to me measured from.

    Edit: Too slow again
