Determine the coefficient of static friction between the friction pad at A and ground if the inclination of the ladder is 0 =60° and the wall at B is smooth when the 82-kg man climbs up the leader and stops at the position shown after he senses that the leader is on the verge of slipping. The center of gravity for the man is at G. Neglect the weight of the leader.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
