1. The problem statement, all variables and given/known data One end of a post weighing 400N and with height h rests on a rough horizontal surface with (mu) = .30. The upper end ish help by a rope fastened to a surface and making an angle of 36.9° with the post. A horizontal force F is exerted on the post. (a) If the force F is applied at the midpoint of the post, what is the largest value it can have without causing the post to slip. (b) How large can the force be without causing the post to slip if its point of application is 6/10 of the way from the ground to the top of the post? (c) Show that if the point of application fo the force is too high, the post cannot be made to slip, no matter how great the force. Find the critical high for the point of application 2. Relevant equations F = ma F_Friction = (mu)N 3. The attempt at a solution (a) Net force = F cosθ -(mu) F Net force = F (cos(36.9°) - .30) Net force = F (~.50) Where to go from here?
