Direction: A 10 mm diameter annealed steel wire is drawn through a die at a speed of 0.5 m/s to reduce the diameter by 20%. The yield stress of the material is 800 MPa.
-
The power required for the drawing process (in kW) is
-
- 8.97
- 14.0
- 17.95
- 28.0
Correct Option: A
| P = Fd × V =357 × | × (8)² × 0.5 | 4 |
P = 8.972 Kw
