How Do You Calculate the Movement of a Hydraulic Lift's Input Cylinder?

Click For Summary
SUMMARY

The discussion centers on calculating the movement of a hydraulic lift's input cylinder based on fluid mechanics principles. The input cylinder has a diameter of 8.00 cm, while the load cylinder has a diameter of 198.0 cm, supporting a mass of 1395 kg. The key equations utilized include the hydrostatic pressure equation and the force-area relationship, specifically F1/A1 = F2/A2. The user seeks to understand the underlying concepts rather than the final answer, emphasizing the importance of incompressible fluid assumptions in the calculations.

PREREQUISITES
  • Understanding of hydrostatic pressure equations
  • Familiarity with the concept of fluid mechanics
  • Knowledge of force-area relationships in hydraulics
  • Basic principles of incompressible fluids
NEXT STEPS
  • Study the derivation and application of the hydrostatic pressure equation
  • Learn about Pascal's principle in hydraulic systems
  • Explore the concept of mechanical advantage in hydraulic lifts
  • Investigate the effects of fluid density on pressure calculations
USEFUL FOR

Students in engineering or physics, hydraulic system designers, and anyone interested in understanding the principles of fluid mechanics and hydraulic lift calculations.

Homework Statement


The input cylinder of a hydraulic lift has a diameter of 8.00 cm, and a bronze lion sits on a cylinder with 198.0 cm diameter. If the lion has a mass of 1395 kg, how far down does the input cylinder have to go to lift the lion 0.500 meter?


Homework Equations



p1 + 0.5 p (v1)^2 + pg(h1) = p2 + 0.5 p (v2)^2 + pg(h2)
F1/A1 = F2/A2


The Attempt at a Solution



This is fluids at rest, so the velocity doesn't come into hand. It doesn't provide p. h1 is 0.5m. What do p1 and p2 equal. They also don't give the force applied on the input cylinder. I don't know how to do this. I don't want the answer. I just want to know how to get there. I'd rather understand the concept behind it.
 
Physics news on Phys.org
Fluids are taken to be incompressible.
 
thanks that makes it much easier
i overlooked that
