Static Equilibrium. We have spent a great deal of time studying motion in all its forms, but now we’re going to step back and look at something called static equilibrium. Simply put, this means unmoving (static), and not about to move (equilibrium).
A stationary object (or set of objects) is in "static equilibrium," which is a special case of mechanical equilibrium. A paperweight on a desk is an example of static equilibrium. Other examples include a rock balance sculpture, or a stack of blocks in the game of Jenga, so long as the sculpture or stack of blocks is not in the state of collapsing.
Learn the definition and conditions of static equilibrium for extended objects, and the lever law for uniform beams. See examples, worked problems and appendix on torques about two points.
When both 3.1 and 3.2 are satisfied we say that the object is in static equilibrium. Nearly all of the problems we will solve in this chapter are two–dimensional problems (in the xy plane), and for these, Eqs. 3.1 and 3.2 reduce to.
