Its time for the annual Edison Tech Center Pi Day Quiz!

**2016 Edison Tech Center Pi Day Quiz**

1) **The Marchant electromechanical calculator** consists of several interlocking gears which are driven by an electric motor. If all the gears have a diameter of one unit, and each gear has ten teeth, what’s the total distance the gears travel for the following calculation:

999+1001

2) The Marchant electromechanical calculator consists of several interlocking gears which are driven by an electric motor. If all the gears have a diameter of one unit, and each gear has ten teeth, **what’s the total distance the gears travel for the following calculation:**

999 multiplied by 1001

3)** In a Synchronous AC motor**, the R.P.M.s are ideally equal to (120 X Freq) divided by the number of magnetic poles.

How fast is the outer material of a 1.5” diameter rotor traveling, when energized at 60 Hz on a synchronous, 4 pole motor?

4) The Marchant electromechanical calculator consists of several interlocking gears which are driven by an electric motor. If all the gears have a diameter of one unit, and each gear has ten teeth, **what’s the total distance the gears travel for the following calculation:**

1001 minus 999

5) A tire company has twenty stacks of tires up to eight tires high, of seven different diameters. **What is the most efficient arrangement of the tires to be able to access any tire?**
