The torsion force example describes how force develops an object when both ends are twisted in the opposite direction. The article discusses with torsion force example listed below:

Drying the Wet Cloth
The Indian drying technique involves tightly rotating the ends of the wet cloth. The twisting on clothes arises due to applied torque or applied moment of force, called ‘torsion force’. The resulting shear stress annihilates the washable water from the wet cloth due to the twisting.

Screwdriver
To fasten and unfasten the screw inside the wall or wooden layout, we rotate or twist the screwdriver on the screw tip to exert the torsion force. Twisting means applying the push or pull force by rotating objects. When we apply a twist on the screw in a clockwise direction, it gets fastened, whereas it gets unfastened if we apply a twist anticlockwise.

Spanner or Wrench
Like a screwdriver, the spanner or wrench is operated to fasten or unfasten a nut that holds the two objects together. The nut appropriately fits at either end of a spanner. Hence, when we turn the spanner, the twist is delivered to the nut – to achieve fastening and unfastening.

Locker
The fastening and unfastening task to be done to lock any system. After inserting the key into a locker, if we rotate it clockwise, the induced twist locks the system. If we rotate it anticlockwise, a similar torsion force unlocks the system.
Jar Lid
While opening a jar or any cylindrical shaped bottle, we supply the rotary motion to its lid or cover by hand. Depending on the twisting direction, the twist torsion force permits the lid to loosen up or tighten up on the jar.
Turning Knob
We need to rotate the knob clockwise or anticlockwise to turn on or off the gas. The knob rotates solely when we employ a torsion force by twisting it. We also observe the torsion force due to knob twisting in many kitchen appliances, like increasing or decreasing the speed of the mixer grinder or heating in a microwave, etc.

Torsion Spring
It is a helical metal spring that stores mechanical energy when twisted. The spring exerts an equivalent force opposite to applied force during twisting. The stored energy is used to offer motion when we release the twist. The small torsion springs are operated in electronics applications, and the large size is operated in the industry.

Old Telephone
Have you noticed that when we turned the dialer to dial the number on the old telephone, it returned to the original position once we released the dialer? It is because of the torsion spring in the dialer. When we dial, the spring stores the energy generated due to twisting, and when we release the dialer, the stored energy helps to regain its original position.

Key Toy
The torsion springs are used to move the toys when we rotate the key several times after inserting and then releasing it. Due to multiple twisting from keys, the torsion force develops the energy, which is then stored in the toy. Once we release the key, the stored mechanical energy is converted into kinetic energy, and the toy starts moving.

Door Hinges
It is fixed above the door that contains a torsion spring to effortlessly open and automatically close. Opening a door produces the twist to the hinges that keep the energy in its torsion spring. Once we remove the twist, the stored mechanical energy is utilized to move the door opposite.

Light Fitting System
The electronic application of torsion force is a light fitting system such as a electric holder. It contains two springs that are employed to hold any electronic bulb. To install or uninstall the bulb into the holder, we require inserting it and then generating a twist by rotating a little to fit it correctly.
Clipboard
It has a torsion spring on the clip mounted on its top. When we press the clip, the spring gets deformed, storing the mechanical energy. When we released the press on the clip, the deformed spring tried to return its original position by utilizing the stored mechanical energy. The clipboard then did the task of holding the papers in position.
Cloth Pin
It also includes a torsion spring to do a similar task like a clipboard. So when we press the pin, the twisting drives the torsion force on it, leading to its deformation and energy stored into the spring. But when we remove our press from the pin, the deformation enables the cloth pin to tie the clothes as per task.
Pendulum Clock
The rotating wheel of the clock offers a twisting to the torsion spring, which stores the mechanical energy. But at a specific time, the wheel pulls the twisting on the spring. That is when the spring utilizes stored energy to drive the pendulum in back and forth harmonic motion.
Retractable Seat
You may have noticed that the seats in the theatres, stadium, hall, etc., are automatically folded when no one is sitting. Such a retractable seat is suitable to use as it saves space. Since a mechanical configuration of torsion spring is attached at the base of a seat, it unfolds when one is sitting and gets folded automatically when no one is using it.

Drive Shaft
The torsion force is a critical factor considered in the automobile engineering design to its smooth movement. It possesses the drive shaft that rotates to transmit the torque induced by the power source, such as the engine, to the wheels.

Steering Wheel
The torsion spring is seen in diverse parts in automobile vehicles such as clutch, suspension, chassis, gearbox, etc. The torsion spring in the steering wheel allows the wheel to return to its initial position after the driver rotates it clockwise or anticlockwise on the curved road.

Suspension Bridge
When a strong wind blows the suspension bridge, it twists to exert the torsion forces that prevent it from breaking. That’s why the torsion test is performed to manufacture such a bridge that scans the amount of force applied and tells us how much tension force the bridge material can bear.

Medical Applications
For various complete tasks, the torsion spring is used in several medical types of equipment like beds, wheelchairs, immobilization devices, etc. The exact operation exerts a torsion force in such applications, permitting flexible motion.
