- Silinda ea hydraulic e na le bophara ba piston ea 4 inches mme e sebetsa ho 1500 PSI.
- Radius = 2 inches
- Sebaka = π × (2 lisenthimithara)^2 ≈ 12.57 lisekoere lisenthimithara
- Matla = 1500 PSI × 12.57 square inches ≈ 18,855 pounds
- Silinda e nyane e bophara ba lisenthimithara tse 2 ka khatello e tšoanang:
- Radius = 1 inch
- Sebaka = π × (1 inch)^2 ≈ 3.14 lisekoere lisenthimithara
