Engineering Thermodynamics

Question

During the operation of lift, it can be subjected to maximum pressure of 500kpa. If it is designed to lift a mass up to 900kg, what should be the diameter of the piston/cylinder?

Engineering Thermodynamics

Answer 1

With the piston at rest the static force balance is

\(\textbf{D}=2\sqrt{\frac{900\times9.807}{500\pi\times1000}}=\textbf{0.149}\)
