Resultant of a force system\n\nThe process of determining a single force that can replace a given system of forces (i.e., the resultant) is called __________ of forces.

Introduction / Context:
In engineering mechanics, two complementary operations are routinely used: finding a resultant (one force replacing many) and splitting a force into components. This question tests your terminology.

Given Data / Assumptions:

• We are asked about the name of the process that yields a resultant force.
• No numerical data are required; this is a definition/terminology check.

Concept / Approach:
Composition of forces means combining multiple forces into a single resultant. By contrast, resolution of forces means decomposing a single force into components along chosen axes or directions.

Step-by-Step Solution:

Verification / Alternative check:
In textbooks, section titles typically read 'Composition of Forces' for resultants and 'Resolution of Forces' for components, confirming the terminology.

Why Other Options Are Wrong:

• Resolution: Opposite operation (one force into components).
• Aggregation / Superposition: General words, not standard technical terms for the operation.
• Equilibration: Introducing equal and opposite forces to achieve equilibrium, not forming a resultant.

Common Pitfalls:
Mixing up composition and resolution due to their frequent paired use. Remember the direction of the operation.

Final Answer:
composition
