Real-Life Applications of Torque

Some real-life objects where torque can be seen are discussed below:

Wrench

Torque is used in wrench for driving screws, bolts, and fasteners into materials. When using a wrench to tighten or loosen a bolt, torque is applied by turning the handle. The longer the wrench handle, the greater the leverage, resulting in more torque being exerted on the bolt. Torque allows the rotational force to overcome the resistance of the bolt and effectively tighten or loosen it.

See-saw

In a see-saw, torque plays a crucial role in balancing the weight of the riders. When one side of the seesaw is heavier, torque is applied around the pivot point as the heavier side descends, causing the lighter side to rise. This rotational force creates the seesaw’s motion and maintains equilibrium between the two riders.

Gyroscope

A gyroscope uses torque to maintain stability and orientation. When a force is applied to change the gyroscope’s direction, torque is generated perpendicular to the applied force, resisting the change in orientation. This property allows gyroscopes to maintain their axis of rotation, making them valuable in navigation systems and stabilizing devices.

Friction Pendulum Bearings

Torque is involved in friction pendulum bearings, which are used in earthquake-resistant building designs. When subjected to lateral forces during an earthquake, the bearings generate torque to resist the building’s movement, allowing it to swing while reducing structural damage and ensuring occupant safety.

Turning on a Tap

When turning on a tap, torque is applied to the tap handle, which rotates the valve mechanism inside. The torque overcomes the resistance of the valve, allowing water to flow through the tap. Adjusting the torque determines the rate of flow of water, controlling the tap’s functionality.

Time Synchronization in Clock

Torque is used in clock mechanisms to regulate the movement of gears and hands. A torsion spring or weight-driven mechanism generates torque, which is transferred through the gear train to control the rotational speed of the clock hands. Consistent torque ensures accurate timekeeping and synchronization.

Hinged Door

When opening or closing a hinged door, torque is applied to the doorknob or handle. This torque creates a rotational force around the hinges, allowing the door to swing open or shut. The amount of torque applied determines the ease of opening or closing the door.

Car Suspension System

Torque is used the car suspension system to absorb shocks and vibrations from the road surface. When encountering bumps or uneven terrain, torque generated by the suspension components, such as springs and dampers, counteracts the forces acting on the vehicle, ensuring a smoother ride and improved handling.
