Magnitude of normal force from ceiling to man

  1. Sep 22, 2012 #1
    1. The problem statement, all variables and given/known data
    tall strongman of mass m = 93 kg stands upon a scale while at the same time pushing on the ceiling in a small room.If the scale reads 1062 N (about 239 lb), what is the magnitude of the normal force that the ceiling exerts on the strongman?



    2. Relevant equations

    N=m x g
    3. The attempt at a solution

    N= 93kg x 9.81= 912 N

    N = mg is not correct. Try drawing a good free-body diagram for the man. You'll need to consider how many forces act on the man and what direction they point.
