Torque Formula:
From: | To: |
Torque is a measure of the rotational force applied to an object. It represents how much a force acting on an object causes that object to rotate around an axis. Torque is a vector quantity, meaning it has both magnitude and direction.
The calculator uses the torque formula:
Where:
Explanation: The formula calculates the rotational force by multiplying the applied force by the distance from the pivot point and the sine of the angle between the force vector and the lever arm.
Details: Accurate torque calculation is crucial in mechanical engineering, automotive applications, construction, and many other fields where rotational forces need to be measured, applied, or controlled.
Tips: Enter force in Newtons, radius in meters, and angle in degrees. All values must be valid (force > 0, radius > 0, angle between 0-90 degrees).
Q1: What is the difference between torque and force?
A: Force causes linear acceleration, while torque causes rotational acceleration. Torque is essentially the rotational equivalent of force.
Q2: Why is the angle important in torque calculation?
A: The angle determines how much of the applied force contributes to rotation. Maximum torque occurs at 90 degrees when the force is perpendicular to the lever arm.
Q3: What are common units for torque?
A: Newton-meters (Nm) in the SI system, and foot-pounds (ft-lb) or inch-pounds (in-lb) in the imperial system.
Q4: How does torque relate to power in engines?
A: Torque measures rotational force, while power (measured in watts or horsepower) is the rate at which work is done. Power = Torque × Angular Velocity.
Q5: What is the right-hand rule for torque direction?
A: Point your fingers in the direction of the lever arm, curl them toward the force direction - your thumb points in the torque direction (perpendicular to both force and lever arm).
