 pump/compressor,

 The pump or compressor converts electrical or mechanical energy into fluid power.

valves,

A valve is a component that controls the direction and amount of flow of the hydraulic fluid or pneumatic air.

actuators

,  Actuators are objects in the hydraulic or pneumatic system that converts fluid power to mechanical power from the cylinders and pistons.

 fluid power system

The fluid power system is the system of hydraulic and pneumatic works and powers, systems of pressurized fluids.

Arch

involves an arch or curve,  may have a Key stone,  compression

Cantilever

projects horizontally, supported on one end;  counterweight 

Compression

squeezing force;  makes things shorter

 Segmental beam

 sections of deck; cables or beams run length; towers to support

 Suspension

 Large primary cable connects two towers; short vertical cables attach to bridge deck. 

Truss

 triangular beam shape; tension and compression, shorter or draw-  bridges common.

Tension

stretching or pulling force; makes longer. 

Describe devices that  use  hydraulics vs pneumatics.

Hydraulic devices use pressurized liquid (such as oil) for heavy, high-force tasks, while pneumatic devices use compressed gas (such as air) for fast, lighter-duty or precision work

Structural

design, plan construct bridges, houses, buildings, power plants..

Geotechnical

analyze soil & rocks,  design foundations, predict settlement …

Water Resources

predict water supply & demand, drainage, runoff, flood prev..

Transporation

GPS sysgems, freeways, traffic controls,

Control:

Both types of systems offer centralized control mechanisms to adjust speed, force, and operational direction
