Magnitude of normal force from ceiling to man

[DOA_Kasumi22]

Homework Statement

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?

Homework Equations

N=m x g

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.
