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

AI Thread Summary
Torque on an object, like a pen, depends on the distance of the force's line of action from its center of mass. When the line of action passes through the center of mass, it generates little to no torque. Forces acting further from the center of mass create greater torque compared to those closer to it. The effectiveness of torque can also be assessed by the perpendicular distance from the pivot point to the line of action. Understanding these principles is essential for ranking the torque produced by various forces acting on the pen.

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.

Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
