An embossing press applies a normal force to a metal sheet using a rectangular stamp.
| setting | normal force in N | contact dimensions in mm |
|---|---|---|
| X | 1800 | 30 × 20 |
| Y | 2400 | 40 × 25 |
Calculate the pressure applied to the sheet by each setting.
The contact dimensions for setting Y remain unchanged. Calculate the normal force that setting Y must apply to produce the same pressure as setting X.
