Physics
Torque
Torque, denoted by τ, measures the rotational force around an axis, with magnitude τ = rF·sin(θ) (the size of the cross product τ = r × F). It's crucial in mechanics for determining the rotational effectiveness of forces. ScanSolve demonstrates step-by-step solutions, helping you ace physics problems.

Frequently Asked Questions
What is the unit of torque?
Torque is measured in newton-meters (N·m) in the SI system, representing the rotational impact of a force.
Does torque depend on angle?
Yes, torque involves the angle θ through sin(θ), affecting how effectively a force causes rotation.
How is torque related to equilibrium?
In equilibrium, net torque is zero, preventing rotational motion and maintaining system stability.
