Document Summary
Chapter 3 equilibrium of a particle. 3. 1 condition for the equilibrium of a particle. Static equilibrium describes an object at rest. To apply the equation of equilibrium, we must account for all forces acting on a body. To do so, we must isolate the body from its surroundings and create a free body diagram. The spring constant, k, represents the elasticity of the spring. F = k(l lo) = ks. Forces due to cables and pulleys. In our studies, cables are assumed to have negligible weight and do not stretch. Cables can only support a pulling or tension force and this force always acts in the direction of the cable. The tension force remains constant over a continuous cable. Drawing a free- body diagram: isolate the body by drawing its outlined shape, add all the forces acting on our body. Example 3. 1: draw a free body diagram for the ring at e, canister a and canister c.
