The 10 m ladder weighing 35 kg is resting on a horizontal floor at A and on the wall at B making an angle of 60° from the horizontal. The coefficient of friction between the ladder and the floor and between the ladder and the wall is 0.25. 1. Determine the distance "x" to which the 72 kg man can climb on the ladder without causing the ladder to slip at its lower end A. 2. Determine the reaction at the wall B. 3. Determine the reaction at the horizontal floor at A.
