Here are 5 examples from everyday life where torque is used.
1. When you twist a bottle lid to open or close it. Same for taps.
2. When you grip and crank a pencil inside a sharpener. Anything with a crank on it works due to torque.
3. When you spin a top by pulling on the thread in a swift motion.
4. When you open / close a door.
Torque is Force x perpendicular distance which is why all door knobs / handles are placed at the farthest end from the hinges to maximise the perpendicular distance and minimize the force (effort) for applying a given torque which opens / closes the door
5. When a car moves away from a stop or accelerates, it is due to torque applied by the engine.

Torque is a measure of how much force acting on the object causes that object to rotate.
● When we twist a bottle lid to open or close it.
● Rotating force when using a wrench to turn a lug nut.
● Rotating force when turning the steering of wheel.
● When we grip a pencil inside the sharpener.
● When we open and close the door.
● When we spin a top by pulling on the thread in the swift motion.
Always remember that -
T = Force * Lever
T = Force * rSin (theta)
