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. Determine the inclination 0 of the ladder if the coefficient of static friction between the friction padA and the ground is µ, = 0.4. Assume the wall at B is smooth. The center of gravity for the man is at G. Neglect the weight of the ladder. %3D
