Question

When analyzing a loaded structure, which concept allows one to replace the loading system with a single equivalent resultant force?

A) Moment equilibrium
B) Shear analysis
C) Resultant force substitution
D) Stress distribution

Answer 1

Resultant force substitution allows one to replace the loading system with a single equivalent resultant force in structural analysis.

Step-by-step explanation:

In structural analysis, the concept that allows one to replace the loading system with a single equivalent resultant force is Resultant force substitution. This concept involves replacing the distributed loads or applied forces with a single force that produces the same effect on the structure. By doing so, the analysis and calculations become simpler and more manageable.
