Which term best describes deforming an object by forming metal through hand methods (stretching and shrinking)?

• A. Hand Forming Techniques
• B. Forging
• C. Casting
• D. Bending

Answer: (A)

Shaping metal by hand through manual manipulation relies on plastic deformation achieved with hands or simple tools, covering techniques that stretch or shrink areas to change geometry without adding or removing material. This broad approach is exactly what “Hand Forming Techniques” describes, since it encompasses the various manual methods used to form metal, including stretching and shrinking. Forging usually implies heating and hammering with dies, often not purely hand-driven; casting involves pouring molten metal into a mold; bending is a specific operation that creates a bend but doesn’t capture the full range of manual forming methods.
