This is really great, thanks so much for sharing your code as well! I'll give this a try and report back.

Thank you both for taking the time to reply. An inflatable beach ball is another example of what I have in mind. @andrewkirk I'm having a bit of difficulty following how each trapezoid will change its shape as you approach the equator. It sounds like the height and width of the trapezoids are...

I ultimately want to make a sewing pattern of a ball. If I have an n-hosohedra, how do I figure out the equation of the curves that make up each lune in 2D?

Your response made me realize I was missing part of the picture. There's also the rest of the loop (including a pool) which contains all of the salt at time zero. I tried solving the problem from the perspective of the pool concentration depleting rather than the tank concentration accumulating...

I have a variation on the concentrating tank problem that I'm having a bit of trouble solving. I have a tank of 10 kg of pure water at time 0. I add a time dependent concentration of salt and remove the same volume of pure water so that the tank volume never changes. Once the tank has 1 kg of...

Thanks for the reply. I admit the 'l' isn't terribly clear in this font, but a little forthought in font choice could prevent the ambiguity. Personally, I find the 'f' more confusing, but maybe that's just me. It seems just as silly to use an 'm' subscript for the liquid phase since liquids are...

I'm curious as to why steam tables typically present liquid properties with an "f" subscript, such as ρf.The gas properties use a "g" subscript, so I would expect the liquid properties to use "l". My first guess at the meaning of the "f" would be that it means "fluid", but this wouldn't make...

Let's say I have two separate 120V AC circuits, each with a triac (15A) that controls a heat element. The first circuit has a heat element that draws a maximum of 1000W. The second circuit heat element draws 2000W. In the first circuit, I leave the triac gate on at all times, and in the second...

I have spent the first five years of my career as a mechanical engineer working for a relatively large engineering company. The company gives me quite a bit of personal freedom, including flex time and generous amounts of vacation. The pay is relatively good and I'm treated well by my peers and...

I imagine you would have a hard time finding a job with those grades, especially if the trend continues through your more advanced courses. You need to figure out why you're having such a hard time. Is it because your job is taking up too much time? It may require that you quit, take out a...

I actually just completed my masters through a distance program. Many schools now support satellite classes. There were even classes that weren't initially setup to be online that were then modified at my request. Most of the courses I took were through a satellite connection where I connected...

Every engineering discipline is challenging. The one you'll find easiest is the one you're most interested in and most passionate about.

Though I don't have direct experience in high school robotics, my guess would be that their either using assembly language or arduino, which is C programming. If you want to know exactly what they're using, call your school. I would recommend buying an arduino and working through the many...

computational skills are not necessary in nuclear engineering, but they will certainly place you in a valuable niche if it's something you enjoy. Python is an excellent language that can be integrated with much of the software used in the industry, especially for data analysis as mentioned...
