A more complete prototype that gives the client an opportunity to test its features is called a(n) model.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
