    Torque Work
AI Thread Summary
Torque does no work when it is balanced, meaning the net torque acting on an object is zero. Additionally, torque can do no work when the angle between the force and the lever arm is 90 degrees, resulting in no movement. Situations where an object is in static equilibrium also lead to zero work from torque. Furthermore, if an object rotates at a constant angular velocity without any net torque, it does not perform work. Understanding these conditions clarifies the relationship between torque and work in physics.

I would like to know all the different situations where torque does no work. So far I only know that torque can do no work when it is balanced. Is there any other ways torque can do zero work?

You should be able to work that out from the definition of work and the definition of torque...
 
Alright then.
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
