• A. Rolling
• B. Forging
• C. Extrusion
• D. Swaging

Hint:

Swaging is a metal forming process where the diameter of a rod or tube is reduced by applying repeated radial hammering or pressing forces from multiple sides. Look for symmetrical force application around a cylindrical workpiece — that’s a key visual clue!

Answer 1

The Correct Option is D

The image depicts a cylindrical workpiece subjected to symmetrical forces from all directions. An analysis of the provided options is as follows:

Option Analysis

- (A) Rolling: This process involves passing material between rolls for thickness reduction or shape alteration. It is inherently directional and not symmetrical, thus not aligning with the image. - (B) Forging: Forging uses dies to apply compressive force, typically from above and below. While it involves high pressure, it does not typically exhibit forces acting simultaneously from multiple sides as illustrated. - (C) Extrusion: In extrusion, material is pushed through a die opening. This is a unidirectional force application, which contradicts the symmetrical forces shown. - (D) Swaging: Swaging reduces the cross-sectional area of a workpiece (e.g., rod, tube) by applying radial compressive forces from multiple directions. This process precisely matches the image, which shows forces acting symmetrically around the cylinder.

Conclusion

The process illustrated in the image is most accurately identified as: (D) Swaging. This is due to the distinctive characteristic of symmetrical compression applied from all sides.
