A uniform thin rod is slightly nudged at B from the θ = 0 position so that it falls to the right. The coefficient of static friction between the rod and the floor is μs.
Figure P7.87
(a) Determine as a function of θ the normal force (N) and the frictional force (F) exerted by the ground on the rod as the rod falls over.
(b) Knowing that the rod will slip when |F/N| exceeds μs, determine whether the rod will slip as it falls.
(c) Plot F/(mg), N/(mg), and |F/N| as a function of θ for 0 ≤ θ ≤ π/2 rad. Use those plots to show that for smaller values of μs end A of the rod slips to the left, and for larger values of μs it slips to the right.
