How Does Torque Depend on the Position of Forces Acting on a Pen?

[Kurwa]

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 don't 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.

I would like to clarify that torque is a measure of the rotational force applied to an object. In order to determine the most torque in this scenario, we would need to know the direction and magnitude of each force acting on the pen. Without this information, it is not possible to rank the forces in terms of torque.

Additionally, the statement "if the line of action passes through the center of mass then there is rarely any torque" is not entirely accurate. While it is true that a force passing through the center of mass will not create a torque, there are other factors such as the distance from the center of mass and the angle at which the force is applied that also affect the torque.

In conclusion, without more information about the forces acting on the pen, it is not possible to accurately determine the most torque. As a scientist, it is important to consider all relevant factors and gather all necessary data before making any conclusions or rankings.
