What is static load?

• A. A load that changes quickly.
• B. Where a worker is holding a large amount of weight with minimal movement.
• C. A load carried by a machine.
• D. A load that is dynamic.

Answer: (B)

Static load is the force that a person applies without movement—holding and supporting a weight in a fixed position. This requires continuous muscle contraction to maintain the posture, which can lead to fatigue in the stabilizing muscles. The described scenario—holding a large amount of weight with minimal movement—fits this idea exactly, since the load stays constant and the body remains largely still. The other descriptions describe loads that involve movement or are carried by equipment, which are not static loads.
