Centripetal force problem involving a washing machine

[QUOTE="kuruman, post: 6408150, member: 192687"] You cannot say that a vertical force is equal to a horizontall force. To clarify in your mind how this works, please answer the following questions 1. What is the sum of all the forces in the vertical direction? 2. What is the acceleration in the vertical direction at the moment the sock is just about ready to slip but has not started moving yet? 3. What is the sum of all the forces in the horizontal direction? 4. What is the acceleration in the horizontal direction at the moment the sock is just about ready to slip but has not started moving yet? You get the two equations I mentioned by setting your answer to 1 equal to mass times your answer in 2 and your answer in 3 equal to mass times your answer in 4. That's how it's supposed to work and don't worry that the mass of the sock is not given. [/QUOTE]
