Question

Longitudinal vibrations are said to occur when the particles of a body moves

Answer 1

Answer:

When the shaft or disc's particles travel parallel to the shaft's axis.

Explanation:

1. The vibrations are known as longitudinal vibrations when the particles of the shaft or disc travel parallel to the shaft's axis.
2. Transverse vibrations occur when the particles of the shaft or disc move in a direction that is roughly perpendicular to the shaft's axis.
3. The direction in which the waves shake distinguishes transverse and longitudinal waves.
4. A transverse wave shakes perpendicular to the movement direction, whereas a longitudinal wave shakes in the same direction as the movement. The vibration of matte causes waves to form.
