AI Thread Summary
Torque is defined as the ability to cause rotation or twisting due to a force applied at a distance from a pivot point. The formula for torque is torque = radius (r) x force (F). The effectiveness of torque increases when the force is applied further from the pivot point, as illustrated by the example of using a wrench. When loosening a nut, applying force at the end of the wrench's handle maximizes torque, while pushing closer to the nut or in a straight line does not generate effective twisting. Understanding these principles is crucial for applying torque effectively in mechanical tasks.

Dear all

I know that torque = rxF, but I don't understand the concept of torque. Would you mind teach me? Thank a lot. Good Bye

It's the ability to twist caused by a force.

Consider a wrench.

If you push on the wrench to loosen a nut you hold it as far down the shaft as possible. If you push when your hand is really close into the nut it won't do as much.

Also, if you push on the nut straight in a line with the wrench you won't cause any twisting either (that's the X term)
 

Thread 'Derivation of Hamilton's Principle: Questions'

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...
