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 with 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 various industrial processes where rotational forces need to be precisely measured and controlled.
Tips: Enter force in Newtons, radius in meters, and angle in degrees. All values must be valid (force > 0, radius > 0, angle between 0-180 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 sin(θ) = 1.
Q3: What are common units for torque?
A: Newton-meters (Nm) in the SI system, pound-feet (lb-ft) or pound-inches (lb-in) in the imperial system.
Q4: How does lever arm length affect torque?
A: Longer lever arms produce greater torque for the same applied force, which is why longer wrenches provide more turning power.
Q5: When is torque zero in this calculation?
A: Torque is zero when the angle is 0° or 180° (sin(0) = 0, sin(180) = 0), meaning the force is applied directly toward or away from the pivot point.
