Question

Okay everyone, I've got a good one here for you.  if you can provide a step-by-step walkthrough on how to do this, itwill be of the most help.   Thanks in advance! P.S. - You'll most likely need the book as I can't cut andpaste the diagrams here without having to re-draw them on thispage, which takes entirely too long for me to do.   Ifyou do need the diagram, I'll post it in a response. Example 4   |   Fighting a Fire In Figure 9-7a an 8.00-m ladder of weightWL = 355 N leans against a smooth verticalwall. The term “smooth” means that the wall can exertonly a normal force directed perpendicular to the wall and cannotexert a frictional force parallel to it. A firefighter, whoseweight is WF = 875 N, stands 6.30 m up fromthe bottom of the ladder. Assume that the ladder’s weightacts at the ladder’s center and neglect the hose’sweight. Find the forces that the wall and the ground exert on theladder. Example 4   |   Fighting a Fire In Figure 9-7a an 8.00-m ladder of weightWL = 355 N leans against a smooth verticalwall.

Find the forces that the wall and the ground exert on theladder.
Figure 9-7   (a) A ladderleaning against a smooth wall. (b) The free-body diagram for theladder. (c) Three of the forces that act on the ladder and theirlever arms. The axis of rotation is at the lower end of the ladderand is perpendicular to the page.

Okay, so the problem asks us to review the above example forreference. The question is: What is the minimum value for the coefficient of staticfriction between the ladder and the ground, so that the ladder doesnot slip?
