Torque Formula:
| From: | To: |
Torque is a measure of the rotational force applied to an object. It represents how much force is acting on an object to cause it to rotate around an axis. Torque is measured in newton-meters (Nm) in the SI system.
The calculator uses the torque formula:
Where:
Explanation: The torque produced is directly proportional to both the applied force and the perpendicular distance from the axis of rotation to the line of action of the force.
Details: Torque calculation is essential in mechanical engineering, automotive design, robotics, and many other fields where rotational motion is involved. It helps determine the twisting force required for various applications and ensures proper functioning of mechanical systems.
Tips: Enter force in newtons (N) and distance in meters (m). Both values must be positive numbers. The calculator will compute the torque in newton-meters (Nm).
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 distance important in torque calculation?
A: The same force applied at a greater distance from the axis of rotation produces more torque, which is why longer wrenches provide more turning power.
Q3: What are common applications of torque?
A: Torque is used in engines, motors, gears, bolts and nuts tightening, and any application involving rotational motion.
Q4: How does angle affect torque calculation?
A: For maximum torque, the force should be applied perpendicular to the lever arm. The formula T = F × d × sin(θ) accounts for the angle between force and lever arm.
Q5: What units are used for torque?
A: The SI unit is newton-meter (Nm). Other common units include pound-feet (lb-ft) and kilogram-force meter (kgf·m).
