The 200- man climbs up the ladder and stops at the position shown after he senses that the ladder is on the verge of slipping.
Determine the inclination of the ladder if the coefficient of static friction between the friction pad A and the ground is = 0.3. Assume the wall at B is smooth. The center of gravity for the man is at G. Neglect the weight of the ladder.
