Trivia Time:

1) Indicated Horsepower is the amount of HP delivered to the top of the piston during combustion and is mathematically calculated. What is Brake Horsepower.
Brake horsepower refers to the amount of usable power delivered by the engine to the
crankshaft.

2) What is the difference between Indicated Horsepower and Brake Horsepower called?
Indicated horsepower can be as much as 15% higher than brake horsepower.
The difference is due to internal engine friction, combustion inefficiencies, and parasitic
losses. The ratio of an engine's brake horsepower and its indicated horsepower is called the
mechanical efficiency of the engine. The mechanical efficiency of a four-cycle diesel is
about 82 to 90 percent.

3) A 4-stroke motor operating at a constant 2100 RPM will complete a single stroke every ____ seconds. (A calculator is permitted)
If a four-stroke engine running at a constant 2100
revolutions per minute (rpm), the crankshaft would be rotating at 35 revolutions, or
12,600 degrees, per second. One stroke is completed in about 0.01429 seconds.

4) When a piston reaches its highest point in the cylinder, this is called what? Conversely, what is the lowest point in a piston's travel called?
The highest point of travel by the
piston is called top dead center (TDC), and the lowest point of travel is called bottom
dead center (BDC). There are 180* of travel between TDC and BDC, or one stroke.

Change of topic so no one person can dominate the trivia game!

5) Ambient air contains approx. __ % Oxygen. An exhaled breath contains __ % Oxygen.
21%, 16%

6) What is considered "normal" blood pressure levels for an adult?
120/80 mmHg

7) During CPR of a person with no pulse present, the rescuer will compress the chest creating a pulse, and there for a blood pressure. If that blood pressure were measured, what would the blood pressure be?
15/0 mmHg

8) Statistically, what day of the week are you most likely to be struck by lightning?
Sunday
BONUS QUESTIONS!

9) What magazine did Huge Hefner work for as circulation manager, while raising funds to start Playboy?
Children' Activities magazine

10) What is the smallest country?
Vatican City is excluded for this question.
This is borederline on a trick question, as the country is not recognized by all sovereign nations, while others have recognized it. There is a fun story behind it for anyone who knows it.
Sealand (someone got this right!!)

(1013.2 millibars) these parameters are referred to as International Standard Atmosphere (ISA) If you change either the altitude, temperature, or barometric pressure, then the amount of oxygen changes... this is referred to as Density altitude. you will lose oxygen as you gain altitude, or as the temperature rises, and also if the barometric pressure falls. Measuring the weight or Density of the air is how a barometer works as does the Altimeter in any aircraft.

So number 5 is a bit of a trick question! Just a bit of fun info!
