Homework Help: Standing on a horizontal beam

  1. Sep 10, 2008 #1
    Standing on a horizontal beam!!!!!!!!

    | \
    | \ rope
    | \
    | \
    |wall \
    | \
    x |w

    a beam is being held up by the rope due to the friction of the wall. the beam has a weight W, and a man is standing x distance away from the wall. the coefficient of friction with the wall is 1/2, the angle is 37*. what is the maximum distance towards the wall that the man can stand without falling.

    i dont know how to start, the only thing i can think of is to use the torque at the angle =[
