Consider the situation shown where a 15-kg box is to be held on a steep vertical slope by a cord that can withstand 80 N. Will the box be held or will the cord snap (i.e. exceed 80 N)? The coefficient of static friction between the box and slope is 0.3. Note: more sophisticated methods exist but do a simple analysis using statics alone and a little reasoning. 60°

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.

Question

Consider the situation shown where a 15-kg box is to be held on a steep vertical slope
by a cord that can withstand 80 N. Will the box be held or will the cord snap (i.e.
exceed 80 N)? The coefficient of static friction between the box and slope is 0.3. Note:
more sophisticated methods exist but do a simple analysis using statics alone and a
little reasoning.
