An engineer checks the work done by four automated presses.
The table shows each work value in kilojoules and its proposed equivalent in newton-metres.
| Press | Work done in kilojoules | Proposed equivalent in newton-metres |
|---|---|---|
| W | 2.4 kJ | 24 N m |
| X | 3.8 kJ | 3800 N m |
| Y | 5.2 kJ | 520 N m |
| Z | 6.7 kJ | 67 000 N m67\,000\ \text{N m}67000 N m |
Write the press for which the proposed equivalent is correct.
Press W
Press Y
Press X
