I know that the centripetal force is the resultant force which points to the center. So in the case of a washing machine, what force pushes the clothes and water to the outer edge? There is not centrifugal force, but then how come all the clothes appear to get pushed to the circumference of the washing machine. I saw something similar in a science museum. There was a rectangular glass prism with water inside. When it rotated about its center, all the water rushed to the edge. I asked my science teacher and he began talking about the centrifugal force. But all the textbooks I have read explicitly state that there is no such thing as a centrifugal force.
