It uses Pascal's Principle, which says pressure that is applied to a fluid is transmitted unchanged throughout the whole fluid. Just an additive, the reason it works is because the pressure is the same but the area is different. This makes the total pressure multiply.
Hydraulic jacks use oil to make it easier to lift heavy objects. moving the jack handle pushes on the liquid in the hose. Liquids cannot be compressed, so the push on the liquid is passed along the length of the hose piston that causes the car to lift a short distance.

Having machines do work that humans used to do.
They relate because they reading involved and how to work the machines and other configurations
Machines such as flour mills used to rely on the moving water of the river to work. Now most milling is powered by electricity, which can be obtained from a variety of sources, including renewable tidal energy.
Pascal's Principle
hydraulic is liquid based, pneumatic is air.
Hydraulic machines rely on the low compressibility of a specific fluid. When the fluid is pumped into the cylinder that does the work and then sealed, the fluid's inability to compress ensures that the cylinder does not lower from the position is was moved to.

a hydraulic system multiplies a force by applying the force to a small surface area.the increase in pressure is then transmitted to another part of a confined fluid, which pushes on a larger surface area
wikipedia
An hydraulic systems uses are to multiply the "effort force" or the force that person is applying to the simple machine
Hydraulic machines are useful in construction as they are force magnifiers. This means that a small input force can be made into a large input force. ^_^

The incompressibility of most liquids.
how is machines related to work
a hydraulic fluid pushes parts to do what you want them to
