AI Thread Summary
Torque directly influences a motor's acceleration, with angular acceleration increasing in proportion to the driving torque. However, when additional load torque is applied, it counteracts the driving torque, leading to a decrease in the motor's RPM. This relationship is particularly evident in squirrel cage motors, where increased load results in slower speeds. The balance between driving torque and load torque is crucial in understanding motor performance. Thus, while torque can enhance acceleration, excessive load can hinder it significantly.

I am wondering how the torque related to its accleration in a motor! If I am not mistaken, by book, the angular acceleration increases proportional to the torque. But, I have done on an experiment, when i add torque to the motor, its RPM decreased...Please tell me why! Thank in Adv.

Can you describe what kind of experiment you did?

Experiment of Squirrel Cage Motor...experiment on the relationship between load torque with the motor speed...
 
Wait, so the more load you apply to the engine the more it slows down? I don't know much about squirrel cage motors but that makes perfect sense to me.

There's torque that tries to speed the motor up (driving torque) and torque that tries to slow it down (load). Increasing the driving torque, as you say, increases the angluar acceleration. Howerver, the load works against the driving torque. Increasing the load effectively DECREASES the driving torque...and thus the angular acceleration/ speed.

If I'm talking about something completely outside of what you had in mind, please correct me...
 

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...
