Learning Objectives

  • 12.01 Distinguish between equilibrium and static equilibrium.
  • 12.02 Specify the four conditions for static equilibrium.
  • 12.03 Explain center of gravity and how it relates to center of mass.

12-2 Some Examples of Static Equilibrium (1 of 6) Link to heading

Learning Objectives

  • 12.05 Apply the force and torque conditions for static equilibrium.
  • 12.06 Identify that a wise choice about the placement of the origin (about which to calculate torques) can simplify the calculations by eliminating one or more unknown forces from the torque equation.
