Force and Motion | Torque and Use of Torque

Ratio of moment of inertia of two object ‘ A’ and ‘B” is 2:3. Which of the following is the ratio of torques of ‘A’ and ‘B’ respectively if both being rotated with constant angular acceleration?

A bar of length ‘L’ pivoted at ‘O’ is acted by force ‘F’ at an angle Θ with vertical line as shown in figure

What is the moment of force

If we double the moment arm the value of torque become

What is the torque in a circular motion?

If the length of a spanner is ‘I’ and force ‘F’ is applied on it to tighten a nut such that it passes through the pivot point, then torque is

If the body is rotating with unifrom angular velocity, then its toque is:

For a body to be in complete equilibrium
