What is the purpose of the spin cycle of a washing machine? Explain in terms of acceleration components

Short Answer

Expert verified

The spin cycle of the washing machine removes the water particles from the clothes.

Step by step solution

01

Concept/Significance of radial acceleration

Points on a rigid body have a centripetal (radial) acceleration(arad) whenever the body is rotating. The expression for the radial acceleration is as follows:

arad=v2r

Here, v is the linear velocity, and is the radius.

02

Determine the purpose of the spin cycle of a washing machine and explain in terms of acceleration components

The main purpose of the spin cycle of the washing machine is to remove the water from the clothes.

The centripetal acceleration of a drum of radius r, rotating with speed v is given by,

a=v2r

This centripetal acceleration is created by the centrifugal force, which removes the water particle on the clothes tangentially outwards through the holes of the drum surface.
