Why torsional pendulum is called torsional pendulum?
A torsional pendulum is an oscillator for which the restoring force is torsion. For example, suspending a bar from a thin wire and winding it by an angle , a torsional torque. (1) is produced, where is a characteristic property of the wire, known as the torsional constant. Therefore, the equation of motion is.
What is moment of inertia in torsional pendulum?
A body’s inherent resistance to rotational acceleration about a specific axis is called its’ mass moment of inertia about that axis. To demonstrate the utility of using a torsional pendulum to determine mass moments of inertia for complex geometries.
How does a torsion pendulum clock work?
The torsion pendulum rotates about the vertical axis of the wire, twisting it, instead of swinging like an ordinary pendulum. The force of the twisting torsion spring reverses the direction of rotation, so the torsion pendulum oscillates slowly, clockwise and counterclockwise.
What is torsional pendulum obtain an expression for its period?
The period of a torsional pendulum T=2π√Iκ T = 2 π I κ can be found if the moment of inertia and torsion constant are known.
How is torsional pendulum different from simple pendulum?
In a simple pendulum, the oscillating mass has dimensions much smaller than the distance between the axis of suspension and the centre of gravity. A torsional pendulum is an oscillator for which the restoring force is torsion.
What is time period of torsional pendulum?
How do torsion clocks work?
A torsion pendulum clock, more commonly known as an anniversary clock or 400-day clock, is a mechanical clock which keeps time with a mechanism called a torsion pendulum. The torsion pendulum rotates about the vertical axis of the wire, twisting it, instead of swinging like an ordinary pendulum.
What is the difference between simple pendulum and torsional pendulum?
