1. 실험 목적
Jet Impact(분사충격)은 고압의 유체를 노즐(nozzle)등을 통해 분사함으로써 에너지를 얻는 기술이다. 보통, 수력 발전소에서 전기를 발생시키는 등 유체의 운동량을 이용하여 동력(power)을 얻기 위함이다. 본 실험을 통해서 유체(물)이 좁은 공간을 통해 분출될 때 발생하는 힘에 대해서 이

FDM - Fused Deposition Molding
FDM works on an "additive" principle by laying down material in layers.
The model is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle.
The nozzle can be moved in both horizontal and vertical directions by a numerically controlled mechanism
nozzle from right to left and instructs the deposition of ink droplets to form a line of drawing or of text. When the paper advances the width of the line, the next pass of the nozzle deposits a slightly different pattern. Thus line by line the complete text or the drawing is formed. After the whole page has been printed, a new sheet of paper is inserted and a new text or a new drawing is created
screw this up, Alex.
I want him in one piece.
Consider it done.
- You okay?
- No, my legs broken!
You got ice on it right away.
That should help.
Lets go before the Russians
get here.
Hey, let me ask you something.
Whatd you do with that plane
that you stole?
Here they come.
Im not talking until you get me out.
- Is that right?
- Yeah.
All right, lets go.
God! Okay! Gundars!
I sold the plane to A
