Tumble dryer problem

timer Asked: Jan 6th, 2019

Question description

Hi guys, I've been stuck on this question for quite a while. The main issue I have is that when i resolve the centripetal force, its vertical component is downwards but in order to offset the downward weight shouldn't it be upwards? Am I doing something wrong? I got 75 revs/min but the answer in the book was 37 revs/min. Thank you.
