Two interconnected hydraulic cylinders can seen as a lever, the smaller cylinder is the end of the lever further away from the fulcrum (where you will apply the force), the larger piston is the load end. Add to that another lever (a brake pedal), you again increase your mechanical advantage. So, at least one of the reasons why hydraulic systems have large mechanical advantages is they combine multiple simple machine concepts to multiply force and torque.

Is a crane a pneumatic or hydrolic system and why?
Older type cranes used pneumatics for the operation of the crane's control systems. The actual movement of the crane's working components are usually operated by hydraulic cylinders or winch systems. The winch systems used to be powered by mechanical friction mechanisms but are typically powered by hydraulic motors today. Typically, pneumatics are never used to power the crane's load bearing functions
Difference between pneumatic and hydraulic machine?
Pneumatic system is operated by compressed air while hydraulic system is operated with pressurised hydraulic oil or any type viscous oil. Hydraulic systems can usually produce higher control forces and work under extreme operating conditions. This is the system that is primarily used on aircraft to move control surfaces and engine controls. You can often classify pneumatic systems because they have a pump (gas pump) and hydraulic systems have a piston. That is the difference. Also, pneumatic systems are louder because it is a gas under pressure. 1. By definition, hydraulics is used in controlling or harnessing power with the use of pressurized fluids whereas pneumatics studies how pressurized gases influences mechanical motion or movement. 2. Hydraulics uses an incompressible fluid medium like oil whereas pneumatics uses a compressible gas like air. 3. Hydraulic applications demand greater pressures during operations that reach thousands of pounds per square inch whereas pneumatic applications only require 100 psi pressures more or less. 4. Most hydraulic applications generally use bigger components that pneumatic applications. 5. Hydraulic systems are generally more difficult to operate compared to pneumatic applications
How do you see the level of a hydraulic excavator?
If you mean to the level of hydraulic fluid, it is usually a glass pipe with indication marks mounted on the hydraulic tank. You can usually find it behind one of the rear access panels.
How is working hydraulic winches?
The hydraulic winches are usually powered by a motor. They can also operate under water.
Why ore of copper is not concentrated by hydraulic washing?
Copper ore, usually in the form of malachite, needs to be refined through a chemical reaction, rather than a mechanical separation as with washing. It needs to be ground and heated to separate out the copper metal from the compound.
Do hydraulic systems depend on air pressure?
Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.

What does bleeder valve mean?
Bleeder valve: Valve, usually operated by a wrench, to release the air from a hydraulic system EG: Hydraulic brakes or Diesel engine injection systems or Early gasoline fuel injection systems or Cooling systems or many other applications that you need to remove air from fluid systems.
What is hydraulic lifts?
Hydraulic lifts utilize a hydraulic piston or ram, typically oil filled, to supply the lifting force for raising or lowering an object/load. These hydraulic systems are usually subdivided by the initial force that drives the hydraulic pump which supplies pressure for the piston. Air/Hydraulics (air over hydraulics) and Electric/Hydraulics (electric over hydraulics) are the two most popular types of power supplies for hydraulic driven systems. Cables and pulleys are often incorporated in hydraulic systems to provide equalization between multiple hydraulic cylinders that must work in unison and to remotely transfer the lifting force to areas where a large cylinder would be impractical to locate.
What is the difference between a hydrostatic and a hydraulic system?
By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".
What do you call machines that use fluid to transmit and increase force?
A machine that runs of of fluid is called a hydraulic.

Where are hydraulic and pneumatic systems used?
Many, many places. Good examples of hydraulic systems include automotive brakes, and the control systems of large aircraft. Pneumatic systems include many types of tools found in an automotive repair shop. Both systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics give high forces with low losses, thanks to the virtual incompressibility of hydraulic fluids. Pneumatics are usually less efficient, though simpler since the "resevoir" in the circuit is the atmosphere. That eliminates return piping and leakage problems.
Can hydraulic pump can be used as hydraulic motor?
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.

Where is the hydraulic pump in a Ford 7600 tractor?
In a Ford 7600 tractor, the hydraulic pump is typically located on the front of the engine, mounted directly to the engine block. It is usually driven by the engine's crankshaft via a belt or gear system. This placement allows for efficient operation, supplying hydraulic fluid to various systems throughout the tractor, including the three-point hitch and remote hydraulic outlets.
