    Rotational Power = torque (τ)*(ω) angular velocity? - Problem with units

    I set up an experiment with a pendulum (uniform beam) swinging on a hinge and the hinge attached to a small PMDC generator. The generator had no load attached and its output voltage is proportional to its speed of rotation. I swung the pendulum from 90 degrees and using a data logger I...

    Flywheel Inverted pendulum torque calculation

    I started building my own flywheel inverted pendulum (i'm using a standard PID controller for the balancing). I came across many articles regarding the differential equation of the pendulum. Most article develop the motion equation using the Euler–Lagrange, few chose the Newtonian way. What I...

    Torque required for synchronising generators

    I had a query a while back on the physics part of MyMathForum. However, I never did manage to resolve it, so hopefully I'll have more success with you guys :) I'm trying to work out the answer to the following problem: Two, four-pole (p=2), 50 Hz synchronous generators are paralleled...

    Finding a position vector of a pivot on a lever from its torque

    Hi guys, I have a problem here which I'm really stumped on. I have a rigid rod of 3.1m length, with two equal masses at either end. The pivot is placed so that the total torque is 25k N.m about the pivot, and I need to find it's location. I've drawn a diagram, a basis, calculated that the...

    diving board torque

    See this image There are 4 forces which are forming which are F1 downwards,(The force which is adding by the bolt) F2 upwards, and the mg and Mg that ate the forces adding by the man and the board. So those forces are taking to calculate the torque of it. But there is a force which is...

    Torque Efficiency.

    Hi all, I need to derive an equation for the efficiency of the gear train in terms of the output load (torque). This train has fixed losses, input power, input and output speeds. Any advice will be appreciated.

    What is torque divided by angular velocity?

    What is the best way to simplify torque as a proportion of angular velocity? Is that even a thing? Is there something close?
