The principle behind the spinning dry of the clothes in a washing machine is centrifugal force.The fast spinnin garound of the clothes in the drum creates a large centrifical force from center to the edge of the drum, and the wet clothes are flung outwards to the drum edge and the water escapes through the drum holes.
