The 180-lb man climbs up the ladder and stops at the position shown after he senses that the ladder is on the verge of slipping. Assume the wall at B is smooth. The center of gravity for the man is at G. Neglect the weight of the ladder.
Determine the inclination θ of the ladder if the coefficient of static friction between the friction pad A and the ground is μs = 0.3.
