In physical risk factors, which description matches static load?

• A. A dynamic force applied repeatedly
• B. A Large Weight Held With Minimal Movement
• C. An Unstable Object In Motion
• D. A Weight Lifting Ability Improvement

Answer: (B)

Static load is a force that is applied and held constant with little or no movement, creating a sustained effort on the body. The description “a large weight held with minimal movement” matches this idea, because the weight is being maintained in a fixed position, requiring continuous muscular contraction without movement. In contrast, a dynamic force applied repeatedly involves changing forces over time and motion, which is dynamic loading. An unstable object in motion also implies ongoing movement and fluctuations, another form of dynamic loading. A description about weight lifting ability improvement talks about capability, not a load condition, so it doesn't describe static load.
