Q. An open coiled helical compression spring 'A' of mean diameter 50 mm is subjected to an axial load ‘W’. Another spring 'B' of mean diameter 25 mm is similar to spring 'A' in all respects. The deflection of spring 'B' will be __________ as compared to spring 'A'.
✅ Correct Answer: (A)
One-eighth
Explanation: When comparing the deflection of two springs with different mean diameters, we use the formula:
