A tool chest has 980 N weight that acts through the midpoint of the chest. THe chest is supported by feet at A and rollers at B. The surface has a coefficient of friction of .320. Determine the value of the horizontal force P necessary to cause motion of the chest to the right, and determine if the motion is sliding or tipping. Can anyone please help me figure out how to solve this?
