    Torque
AI Thread Summary
The discussion revolves around comparing torque produced by different gear configurations. Specifically, it questions whether the torque from a 20-tooth gear driving a 60-tooth gear is equivalent to that from a 60-tooth gear driving another 60-tooth gear. The conversation emphasizes the importance of calculating the effective radius at the contact points and understanding lever arms in these scenarios. The mention of "infinite torque" suggests a theoretical exploration rather than practical application. Ultimately, the focus is on the mechanics of gear interactions and torque calculations.

Hello
so here is the problem that I'm confused with:
let's say...

Will a torque produced by a 20 teeth(force is exerted to this one) to 60 teeth gear be the same torque compared to a 60 teeth(force is exerted to this one) to a 60 teeth gear.

My torque is infinite, my friend.
 
Calculate the effective radius of the contact points on the theeth of the two gears, and use your knowledge of lever arms.

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...
