Transcript of hydraulics.

Definition Of Hydraulics.
The branch of science and technology concerned with the conveyance of liquids, through pipes and channels, especially as a source of mechanical force or control. Hydraulics systems or forces. "The lift is driven by hydraulics."
This is a video to show you a little about hydraulics.
How Hydraulics Work:
Hydraulic machines are machinery and tools that are use liquid fluid power to do simple work.

Real Life Examples Of Hydraulics.
Working Model of Hydraulics:
Hydraulics work through a system of fluid mechanics using compressors cylinders. Hydraulics mechanics are used for lifting heavy objects.
The brakes on your car.
A car jacked with oil.
Flaps on an airplane are moved by hydraulics.
Car crusher.
Bobcat tractors.

The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses and the high power of density and wide array of actuator that can make use of this power. Hydraulics machinery is operated by the use of hydraulics, where liquid is the powering medium.
Example~ heavy equipment in this type of machine, hydraulics fluid is transmitted throughout the machines to various hydraulics motor and hydraulic cylinders and which becomes pressurized according to the resistance present. By controlled directly or automatically by control valves and distributed through hoses and tubes.

Step 1: Write down the equation needed to solve the problem.

Step 2: Insert all known measurements into the equation.

Step 3: Solve. Carefully enter numbers into your calculator.

work = force x distance or W = F x d

• The SI unit for force is newton (N).

• The SI unit for distance is meter (m).

• The SI unit for work is joule (J).

Calculating Force and Work.

Mechanical Advantage.
MA = length of effort arm ÷ length of resistance arm
Mechanical Efficiency.
Definition: The mechanical advantage (MA) is the factor by which a machine multiplies the force put into it.
Mechanical efficiency measures the effectiveness of a machine in transforming the energy and power that is input to the device into an output force and movement. Efficiency is measured as a ratio of the measured performance to the performance of an ideal machine:

Efficiency = Measured Performance/
Ideal Performance
