A uniform ladder of weight `W` and length `L` is resting between rough floor and smooth vertical wall. The ladder makes an angle `53^(@)` with horizontal. A man of weight `3W` climbs the ladder and stays at distance `L//3` as shown. (a) Find the normal and friction force on the ladder at its base. (b) Find the minimum coefficient of the static friction needed to prevent slipping at the base.
