Which deformation method involves the object being compacted?

• A. Stability
• B. Compression
• C. Tension
• D. Torsion

Answer: (B)

Deformation by compression is when forces act toward each other from opposite sides, pushing the material inward and causing it to shorten and pack more tightly—that’s what “compacted” means. This is exactly the scenario described. Tension would pull things apart and elongate them, torsion twists the material around its axis, and stability is about resisting deformation rather than describing a specific deformation mode. So the method that produces compaction is compression.
