The four strokes in one cycle of a 4-stroke internal combustion engine?

Explain the Venturi Principle, and give two examples of its use in practical, real-world situations.

Explain the term "bored and stroked" in relation to engines.

What is the difference in an engine and a motor?

Name three measurement systems used to denote which wrench/bolt/nut is which size.

What is "viscosity"?

What are 4 purposes of "motor oil"?

ETA:  here's what I was looking for -- let me know if I'm totally wrong, OK?

Intake, compression, power, exhaust (OR the mnemonic I learned:  suck, squeeze, bang and blow).

Venturi Principle:  See duane_kc  's answer; add the carved wooden screens that were in use in the Middle East for years to cool the air in buildings.

Bored and stroked -- the cylinder drilled out to accommodate a larger diameter piston, and the throw of the crankshaft and the connecting rod increased to lengthen the distance a piston travels.  Increases available power.

Engine takes a substance such as gasoline and converts it to motion (or "power"), motor converts one sort of power/energy (electricity) to another (rotation).

SAE, Metric and British Whitworth are three options.  There may be many more for all I know!

Thickness of a liquid such as oil or paint.

Clean, cool, seal, and lubricate.


No google, no peeking. 

Open House

Well, got through that intact...but severely over-peopled!  The other MT was in Branson for the day, so I had the pleasure (and pleasure it was) to do 5-minute "free samples" and handed out cards and did a couple of brief aromatherapy consults.

Also got one appointment set up!  And a definite time/day for a swap :D

The Studio end of the building has VERY bad acoustics -- anything going on is very audible in all areas and the tile floor seems to raise the volume, so with the Zumba music going and 15 people all talking over it and each other...yeah, I was overstimulated.  Left stuff as it was and locked up; went back today to clean and pack up.

Also had to tighten the screws that hold the seat to the frame on the massage chair -- wonder how often I'll have to do that.  It's an NRG brand, any input on that?  (I want a Dolphin ii eventually!)
