Equilibrium 01/08/2018 LO: Define equilibrium Investigate triangles of forces

When an object is in e_________ the resultant force will always be ____. If a diagram is drawn to add three forces in equilibrium, they will always form a ________.

Statics and Dynamics Mechanics is concerned with the forces acting on a body. When the forces are balanced, the body is said to be in equilibrium. The branch of mechanics that deals with such cases is called statics. The branch of mechanics that deals with cases not in equilibrium is called dynamics.

When there is no acceleration (Constant velocity) Where else could a system be in equilibrium but not static? When there is no acceleration (Constant velocity)

Use the rules of equilibrium to determine the weight of a hammer.
