### An IQ test, Part II

1. How many cylinders does the most common Cummins Diesel have?
2. In what make of pickup truck is this engine offered as the premium engine?
3. Is premium gas is specified for that engine? If no, why not?
4. If you went on a safari, would you be more likely to go to Zaire, Zimbabwe or Zambia?
6. What are the actual thickness and width of a 2-by-4?
7. What is the name of the person who empties your wastebasket?
8. What is their nationality?
9. Do they have any kids?
10. What do "AC" and "DC" power refer to?
11. Can you put a typical AC motor into reverse by reversing the polarity?
12. Can you put some AC motors into reverse by switching a pair of wires?
13. The most commonly encountered AC motors run on XXXX Voltage. What is that Voltage?
14. The most commonly encountered DC motors run on YYYY Voltage. What is that Voltage?
15. Name the state where world famous blogger C.W. Swanson lives.

1. Six cylinders.
2. Dodge
3. It is a diesel, stupid. It doesn't run on gas.
4. Zambia. Zaire was renamed and Zimbabwe is too dangerous for safari.
5. Given the paucity of cracked heads in the MSM, we are forced to surmise the answer is "Zero".
6. 1.5 inches by 3.5 inches.
7. Varies. This person is privy to most of your secrets. If you don't know his/her name, why?
8. This person was probably not born in the United States but is probably proud of where they came from.
9. This person is privy to your boss's secrets and can give you a heads up about when you are about to be fired. Why don't you know anything about them?
10. AC and DC refer to electrical power. AC stands for "Alternating Currrent" where the voltage of one wire varies in a sinusoidal fashion relative to the other wire. That relative voltage alternates between positive and negative. DC is direct current and it does not alternate between positive and negative.
11. No.
12. Yes. You can reverse the direction a 3-Phase, inductive, electric motor turns by reversing one or three pairs of wires.
13. Most AC motors you encounter in your home or office run on a nominal 110V voltage.
14. Most DC motors will be encountered in mobile equipment and run on a nominal 12V voltage.
15. California.
