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 coefficient of static friction between the friction pad at A and ground if the inclination of the ladder is at theta=60 degrees and the wall B is smooth. The center of gravity for the man is at G. Neglect the weight of the ladder
