A cylinder hydraulic press has a small piston with a diameter of 3 m, and the diameter
of the large piston is unknown. Suppose a force of 800 N is applied onto the small
piston to lift the 250 kg load. The hydraulic press follows Pascal principle.
i)
Calculate the diameter of the large piston.
ii)
Estimate the force needed if additional load of 50 kg is added.
i) The diameter is
The weight the force of the piston must overcome is
Find the mechanical advantage:
Here a - the area of the smaller piston. Hence:
ii) The force is
