1. The problem statement, all variables and given/known data [PLAIN]http://img24.imageshack.us/img24/8382/fm1u.png [Broken] 2. Relevant equations µ ≥ tan Θ 3. The attempt at a solution I'm new here, if I post something wrong here. please correct me!! :) I don't understand the question. Where is the normal reaction between the rod and the floor? from figure 1. Is it in the same direction as the rod acting on the floor? or perpendicular to the floor? If the normal reaction is same as the direction as the rod acting on the floor then: Resolve vertically - R cos Θ = W Resolve horizontally - R sin Θ + F = ? F ≤ µR F ≤ µW / cos Θ ? is it correct?
