The force applied to keep a load stationary during rigging is called the ?.

• A. Friction
• B. Lifting
• C. Static
• D. Shear

Answer: (C)

When a load is not moving, the system is in static equilibrium—the forces acting on it balance so there’s no acceleration. The force you apply to keep it from moving is a static force, reflecting that stationary condition. This contrasts with dynamic loads, which come from movement or acceleration, and with friction, which is the resisting force at contact surfaces rather than the act of holding the load in place. Lifting describes the action of raising, and shear refers to internal sliding forces within materials. So the best match for the held-in-place force is static.
