A torsion pendulum is composed of a very thin flat strip of metal like phosphor bronze or steel with a metal bob connected to the lower end. The top is fixed to a stable beam and the bob is then rotated and released. This has slightly raised the bob and has stored some torsional energy in the metal strip. It is then free to return to it's resting position,it overshoots and when halted by torsion in the opposite direction reverses and so on until all the torsional energy applied in the initial turning is dissipated. Cars and motorcycles also use torsion bar suspension system where a steel bar is rigidly fixed at one end to the chassis and the wheel hub, at the end of a cranked arm, is pivoted at the opposite end of the torsion bar. The vibrational energy of the wheel arm moving up and down over bumps in the road is stored as a twisting energy in the torsion bar. This then restores as it untwists and acts like a longitudinal spring.
What else can I help you with?
Which oscillations are seen in torsion pendulum?
In a torsion pendulum, torsional oscillations are observed. These oscillations involve the twisting of a wire or shaft that suspends the pendulum mass, resulting in a rotational motion back and forth. The restoring force for these oscillations comes from the torsional stiffness of the wire or shaft.
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.
Why a compound pendulum is called an equivalent simple pendulum?
A compound pendulum is called an equivalent simple pendulum because its motion can be approximated as that of a simple pendulum with the same period. This simplification allows for easier analysis and calculation of its behavior.
What is a complete swing of a pendulum called?
A complete swing of a pendulum is called an oscillation or a cycle. It consists of the pendulum moving from one side to the other and back again.
Why a compound pendulum is called equivalent simple pendulum?
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
What is the value of the rigidity modulus of the brass wire by usiny torsion pendulum?

What does the term 400 day clock mean?
A 400 day clock is another term for a torsion clock which is a device that keeps time using a torsion pendulum. It is also known as an anniversary clock.

What is the swinging mass called at the bottom of pendulum?
Any terminal object such as the weight on a pendulum is known as a Bob. It can also be called a Mass
What is the name of the bottom of the pendulum swing?
The bottom of the pendulum swing is called the equilibrium position.
What machine converts gravitational energy into elastic energy?
A gravity-powered clock, such as a grandfather clock or a torsion pendulum clock, converts gravitational energy to elastic energy using a weight-driven mechanism. The weight slowly descends due to gravity, causing the clock's spring or pendulum to wind up and store potential energy as tension in the spring or material of the pendulum.
The time required for a pendulum to make one swing over and back is called its?
The time required for a pendulum to make one swing over and back is called its period. It is the time it takes for the pendulum to complete one full oscillation.
