Question

show that bigilar oscillation are SHM derive the expression for periodic time of bifilar oscillation with parallel threads​

Answer 1

Answer:A bifilar pendulum consists of suspending an aircraft from two parallel wires, or filars, that. allow it to rotate freely about a given axis. The experiment is to measure the moment of inertia for the axis of rotation parallel to the filars.

Explanation:

Answer 2

Answer:

• A heavy and uniform metallic plate comprises the bifilar pendulum.
• Each face of the pendulum is provided with a pair of holes, symmetrically situated on either side of the center of the face.
• By the means of a torsion less string and a rigid support, the body of the pendulum is suspended mid-air.
• When the body is twisted through a small angle in the horizontal plane and released, it executes simple angular oscillations about the vertical axis passing through its center of gravity.
• The distance between the strings can be changed by using the screws on the rigid support and the bifilar pendulum can be suspended in any orientation be it vertical or horizontal.

Thus, it proves that the bifilar pendulum performs Simple Harmonic Motion.
