Question

Cold working process can be applied on the components having diameter up to:

• A. 12 mm
• B. 25 mm
• C. 49 mm
• D. 50 mm

Hint:

Cold working is effective for materials with smaller diameters, typically up to 25 mm, due to the limitations of applying sufficient force at room temperature for larger components.

Answer 1

The Correct Option is B

Cold working is a process that is done at room temperature, and it is typically used for shaping materials like metals by applying compressive forces. The diameter limit for cold working is dependent on the material properties and the type of operation.
- 12 mm is too small for most cold working processes. Cold working generally applies to larger components.
- 25 mm is the correct answer. Cold working can be effectively applied to components having a diameter up to 25 mm.
- 49 mm and 50 mm are too large for cold working to be easily applied using conventional methods. Larger diameters would require high amounts of force and could be difficult to deform at room temperature.
Thus, the maximum diameter for cold working processes is typically around 25 mm.
