What is the modulus of rigidity of wire by using torsion pendulum?
The modulus of rigidity of a wire can be calculated using a torsion pendulum experiment by measuring the angular deflection of the wire under a known torque. By relating the torsional constant of the wire, the length of the wire, and the applied torque, the modulus of rigidity (also known as shear modulus) can be determined using the formula G = (π * r^4 * T) / (2 * L * θ), where G is the modulus of rigidity, r is the radius of the wire, T is the torque, L is the length of the wire, and θ is the angular deflection.
Why torsion pendulum is called so?
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?
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.
How to find the gravitational constant?
The gravitational constant, denoted as G, can be found through experiments involving the measurement of the gravitational force between two objects with known masses and distances. One common method is to use a torsion balance, which measures the twisting of a wire due to the gravitational attraction between two masses. By analyzing the data collected from these experiments, scientists can determine the value of the gravitational constant.
What is the word for the meaning 'a flexible strand of metal'?
The word for a flexible strand of metal is "wire."

Is bending a metal wire a chemial or phyiscal change?
Physical. The metal wire is still a metal wire after the change.
How does torsion effect a bridge?
There are 3 ways to prevent rusting A. Plate the metal with another metal, expensive. B. Paint or coat the metal with a chemical that prevents the metal from getting wet. C. Chemically treat the metal so it can only rust a little and it cannot rust through. Depending on what you are working with would determines the method you use.
Who find the value of gravitational constant?
Gravitational constant was determined by lord Henry cavendish in 1798 using a torsion balance .....G=6.67 *10^-9
What are metal springs?
Metal springs are mechanical devices made of coiled metal wire that store mechanical energy when compressed or stretched. They are commonly used in various applications to provide flexibility and reduce the impact of forces or vibrations. Springs come in different types, such as compression, extension, and torsion springs, each designed for specific purposes based on their unique properties.
What is the metal used in wire?
In most cases, copper is the metal used in wire.
Dielectric constant of metal is?
The dielectric constant varies, depending on the material.
What is thicker 28 or 30 gauge?
The thickness of metal wire is inversely proportional to the guage number of the metal wire. So 28 guage metal wire is thicker than 30 guage metal wire.
Is baling wire a metal or nonmetal?
Baling wire is a metal, specifically a type of steel wire used for bundling materials like hay or straw.
