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.

Which oscillations are seen in torsion pendulum?
Circular harmonic motion
Why it's better compound pendulum than a simplependulum?
because in simple pendulum we say that we use a torsion less thread which of negligible mass but actually it's not negligible but in compound pendulum we don't such type of negligible materials hence it's better than the first one
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.
What is the difference between torsion force and tension force?
if the force twists an obect, it is called torsion and if the force that stretches an object is called tension.
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?

Which type of motion is exhibited by tortional pendulum?
A torsional pendulum exhibits rotational periodic motion. You can create one by hanging some weight from a cord, and then rotating the weight. The cord becomes twisted, generating a torsion force, that will cause the weight to rotate in the oppopsite direction. Thus, a periodic rotation movement is generated.
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 swinging bit on a clock called?
Pendulum
How do you split pendulum into syllables?
Pendulum is split into syllables like so: pen-du-lum.
What is the mean position of the pendulum?
The time it takes a pendulum to complete one full cycle from one side to the other and back again is called its period. The angular distance swept by a pendulum as it swings from one side to the other is called its amplitude.
If a pendulum is made to swing in water compare the time taken for this pendulum to come to a complete stop with the time taken by a pendulum swinging in air?
A swinging pendulum encounters "friction" called drag in air. It will do so in water, too. It's just that the viscosity of the air is so much less than that of water, so the pendulum moves with a ton more drag in water. It will move much more slowly in water, and will come to a stop dramatically sooner than an identical pendulum swung in air.
