A forming press pushes a metal component downwards in three stages. The downward force is constant during each stage.
| Stage | Downward force | Distance moved downwards |
|---|---|---|
| initial compression | 12 000 N12\,000\ \mathrm{N}12000 N | 8.0 mm |
| final shaping | 20 000 N20\,000\ \mathrm{N}20000 N | 4.0 mm |
| held in place | 20 000 N20\,000\ \mathrm{N}20000 N | 0 mm |
What is the total work done on the component by the downward force?
