Torque
Torque, denoted by τ, measures the rotational force around an axis, given by τ = r × F × sin(θ). It's crucial in mechanics for determining the rotational effectiveness of forces. ScanSolve demonstrates step-by-step solutions, helping you ace physics problems.
How to Approach Torque
Input force and distance
Enter the magnitude of the force (F) and the lever arm distance (r) in meters.
Specify angle of force
Indicate the angle θ between force direction and lever arm to calculate sin(θ).
Compute torque value
Find the torque τ using the formula τ = r × F × sin(θ), showing each calculation step.
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.
