Homework Help: Problem in statics

  1. Apr 2, 2010 #1
    1. The problem statement, all variables and given/known data

    A man holds a 6-kg uniform plank. Determine forces at A and B. A is at 1 end of the board and B is 0.6 metres further down. total lenght is 1.4 m

    2. Relevant equations

    w=mg
    M=fd

    3. The attempt at a solution

    there will be a force down at A and up at B. i think A will just be weight. So 58.9 N not sure about B though.

    i think i might have it. A is down so is weight so B is just these two added together?
