Double-check calculations for critical applications.

Learn More About Torque

Scientific Overview

Torque is the rotational equivalent of linear force. It measures the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Torque is a vector quantity calculated as the cross product of position and force vectors.

Historical Background

The concept of torque was developed by Archimedes in his work on levers. The term "torque" comes from the Latin "torquere" meaning "to twist". James Watt first used torque measurements in his steam engine improvements.

Real-World Applications

Mechanical Engineering

Torque specifications are critical for bolt tightening and mechanical assemblies.

Automotive

Engine torque determines vehicle acceleration and towing capacity.

Robotics

Joint torque control enables precise robotic movements and force feedback.

Sports

Torque generation is essential in golf swings, baseball bats, and other rotational sports.

Interesting Facts
