What term describes the act of holding something in place by adhesive or mechanical means?

• A. Retention
• B. Sorption
• C. Adhesion
• D. Locking

Answer: (A)

Retention is the act of keeping a part fixed in its position using adhesive or mechanical means. It covers how a component is held in place—from bonding with glue to securing with fasteners or clamps—so it stays where it’s supposed to under use. Adhesion describes the attraction between surfaces, which is part of how things stick, but not the overall action of maintaining position. Sorption is about taking in substances, which isn’t relevant here. Locking refers to a specific mechanism to prevent movement, but retention is the broader idea of keeping something secured in place by adhesive or mechanical means.
