Question
Dear Prof Scott

Is it possible to design a Ferris wheel electronic toy operated by a remote control and having push buttons to control the start, stop, increase, decrease the Ferris wheel speed?

Thanks
Prashant

Answer
To view a few, just type, "Ferris Wheel," in the search box.  I not only answered this question, but answered so much more.  I'm very interested in them.  Perhaps that is because I constructed one out of toothpicks and glue in high school that was over half a meter across.  The seats were made out of popsicle sticks that were each cut to one fourth of their length.

I'm sure it is.  It has to involved a noticeable amount of energy since the Ferris Wheel is so large.  The bigger the Ferris wheel is, the more power it required to turn it.  Some of them are fairly large.  It seems like compared to the power it takes to move them around, the power to make all the lights on them is insignificant.

The one in London, England was the largest in 2006.  I would guess there are at least 40 seats on it.  From what I remember of the one I see at the fair every year, most of them have around a dozen seats.

There are a few that are built out of Legos, some built out of small electronic kits, some built out of cakes, some are designed to look at on the computer screen, and probably even more stuff than that.  Some are used to hold an advertisement on the side.

As far as the seating, most either have seats or baskets.

Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

Experience

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors in both my BS and MS degrees. Past/Present Clients: College Students at Oregon State University, various math people since college, over 7,500 people on the PC from the US and rest the world.

Publications
My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials
Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors
I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes in mathematics, I was first. In a class of over 100 students, I was always one of the first ones to complete the test. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients
My clients have been students at OSU, people who live nearby, friends with math questions, and several people every day on the PC. I would guess that you are probably going to be one more.
