The maximum possible percentage reduction in area per pass during wire drawing of an ideal plastic material without friction is of the order of
-
- 37
- 50
- 63
- 75
Correct Option: C
| σd = σ0 |  |  | |
| Af |
| = R → Extrusion Ratio | |
| Af |
If σd = σ0 {Maximum possible Reduction}
| 1 = ln | | | |
| Af |
| e = | |
| Af |
| % Reduction = | × 100 = | | 1 − | | × 100 | ||
| Ai | e |
% Reduction = 63%
