It will remain at rest or continue moving with a constant velocity. 3 Forces in Equilibrium Resultant-Equilibrant Select 2 forces and find their resultant. The remaining force is called an equilibrant if it is equal and opposite the resultant. Triangle of Forces Three forces are in equilibrium if they can be arranged to form a triangle. Three or more forces are in equilibrium if they can be arranged to form a polygon.
Components Resolve all forces into components in some convenient coordinate system.
Combine the components along each axis. If the resultant along each axis is zero the object is in equilibrium. Problems numerical A push broom of mass m is pushed across a rough horizontal floor with constant velocity by a force of magnitude F directed at an angle q with respect to the floor. Make a free body diagram showing all the forces acting on the head of the broom. Find the coefficient of kinetic friction on the broom in terms of the variables m , g , F , and q .
