Magnitude of normal force from ceiling to man

AI Thread Summary
The problem involves a strongman with a mass of 93 kg standing on a scale while pushing against the ceiling, which reads 1062 N. The normal force from the ceiling can be calculated by analyzing the forces acting on the strongman, including his weight and the force he exerts on the ceiling. The equation N = mg was initially considered but deemed incorrect without a proper free-body diagram. A comprehensive understanding of the forces and their directions is necessary to determine the correct normal force exerted by the ceiling. This analysis will lead to the accurate calculation of the normal force in this scenario.

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.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
