A sheet metal drawing is considered feasible if the following conditions are met:
- Reduction ratio < 0.5
- Thickness to diameter ratio > 1%
A sheet metal drawing process is being planned on a sheet metal with a thickness of 2 mm with a punch of diameter 100 mm with various blanks of diameter \( D_b \).
Which ONE of the following blank diameters \( D_b \) (in mm) will result in feasible drawing?
