In a two-stage wire drawing operation, the fractional reduction (ratio of change in crosssectional area to initial cross-sectional area) in the first stage is 0.4. The fractional reduction in the second stage is 0.3. The overall fractional reduction is
-
- 0.24
- 0.58
- 0.60
- 1.00
Correct Option: B
40% Reduction = 1 × 0.4 = 0.4
30% Reduction of 0.6 = 0.6 × 0.3 = 0.18
Total Reduction = 0.58
