Static Equilibrium Tension Torque Lever Beam. The solution to some equilibrium problems can be simplified if we recognize members that are subjected to forces at only two points (e.g., at points A and B). If we apply the equations of equilibrium to such a member, we can quickly determine that the resultant forces at A and B must be equal in magnitude and act in the opposite directions along, Equilibrium: Until motion begins, all forces on the mower are balanced. Friction in wheel bearings and on the ground oppose the lateral motion. Objectives: After completing this module, you should be able to: • Define and calculate the coefficients of kinetic and static friction, and give the relationship of friction to the normal force. • Apply the concepts of static and kinetic friction.
