Question
Question Part Points Submissions Used The figure below shows a vertical force applied tangentially to a uniform cylinder of weight Fg. The coefficient of static friction between the cylinder and all surfaces is 0.500. The force is increased in magnitude until the cylinder begins to rotate. In terms of Fg, find the maxi mu m force magnitude P that can be applied without causing the cylinder to rotate. Suggestion: Show that both friction forces will be at their maxi mu m values when the cylinder is on the verge of slipping. (Use any variable or symbol stated above as necessary.)
Explanation / Answer
NOrmal force = Fg-P
Frictional force = .5(Fg-P)
For rotation to impend , tangential force = frictional force
P = .5(Fg-P),
P = Fg/3
