Four different cylindrical pistons, W, X, Y, and Z, in an experimental engine block are subjected to different gas forces. The force applied to each piston and its cross-sectional dimension are shown in the table:
| Piston | Applied force | Dimension |
|---|---|---|
| W | 150 N | Radius = 5.0 mm |
| X | 240 N | Diameter = 12.0 mm |
| Y | 80 N | Radius = 3.0 mm |
| Z | 400 N | Diameter = 16.0 mm |
Which piston experiences the greatest pressure?
Piston X
Piston Y
Piston Z
Piston W
