Applications of the Principle of Moments in Everyday Life

1. Turning a Car Steering Wheel
   • One hand applies a clockwise moment, while the other hand applies a counterclockwise moment to turn the wheel in the desired direction.
2. Using a Screwdriver
   • A moment of force is applied to turn screws, making it easier to insert or remove them.
3. Using a Spanner
   • A spanner is used for tightening or loosening nuts and bolts by applying a moment of force.
4. Opening and Closing a Door
   • Applying force at the handle (which is far from the hinges) creates a moment about the hinges, making it easier to operate the door.
5. Playing on a Seesaw
   • Each person exerts a moment about the pivot, and balance is achieved when the moments are equal on both sides.
