Homework Statement


Assume you have a pen- where its center of mass is directly in the middle of the pen. There are about 6 forces acting on it from different angles....

how would you rank the most torque


all forces are equal of magnitude.

The Attempt at a Solution



im using this fact- if the line of action passes through the center of mass then there is rarely any torque.. and also if the line furthes from the center of mass has the largest torque compared to the forces that are close to the center of mass but dont cross it.

soo am i right or am i wrong ?

First of all if by rarely you mean zero, then that is correct.

The other torques may be judged by their distance away from the pivot through any line that makes a perpendicular with the pivot.
