It's centrifical force - and that is used when the closthes spin dry. The smaller and faster the bucket - the dryer the clothes are going to be when they come out of the washing machine.

Centripetal force is the force which keeps any object in circular motion.
In washing machine, whenever the clothes are in circular motion the drums provide the necessary centripetal force to keep them in circular motion.

In the drums there are holes and the holes cannot provide the centripetal force.
When the drum is rotated with high speed, water particles acquire linear speed and the speed is high so that they move in a spiral path. The radius of the circular path is increasing corresponding to the speed.
Thus, it is the lack of necessary centripetal force, the water particle move away from the center. Actually they move along a tangential path and not along the radius.

If we shift our reference frame to the rotating drum, then with respect to this new reference frame, we can say that the objects in the drum are moving under a force
which is also called centripetal force.

But this centripetal force is different from the centripetal force if the reference frame is the ground in which the machine is set up. In that reference frame the centripetal force is one which is not acting on the objects inside the drum; it is acting on the object which is providing the centripetal force.

Now with respect to the new frame of reference the centripetal force is the force which makes the water particles move away from the center through the holes.
The clothes are retained in the drum due the reaction of the drum acting on the clothes.

With respect to the frame of reference in the ground, the clothes move in circular path due to centripetal force and water particles move out of the drum for the lack of centripetal forces.

The spin cycle. the clothing will not greater healthful for the duration of the holes interior the bathing device's drum however the water will. this potential that jointly as the bathing device is in a position to exert a centripetal rigidity on the clothing, the water absorbed by potential of the clothing would not have an identical quantity of rigidity exerted on it so it strikes far off from the axis of rotation (and out of the clothing)

During the spin cycle, the drum provides centripetal force to keep the fabrics moving in a circle, while holes in the drum allow water to escape by not providing centripetal force to the water.

If you look inside the machine, there are holes in the walls. When the the machine is in the spin cylcle, centripetal force causes excess water to move radially outward and drain away from the clothes.

Do you mean centrifugal force? In a top loader it would come into play during the spin cycle - the force pushes the clothes against the outside of the tub and squeezes the water out.

I would assume that the spin cycle is there to purge the dirty water and allow for the rinse cycle to do an effective job of cleaning. Plus it spins out the water used to rinse so that they aren't dripping wet when you open the washer.

Sorry that wasn't completely scientific.

Ok, Ill bite. What is Centripetal? Did you, perhaps, mean centrifugal? Centripetal might be that stuff that hangs onto the agitator looks like a petal to some flower? Or mabe if it goes fast you put the centripedal to the metal.. I dunno..
