    I How do I create a sewing pattern for a spherical lune in 2D from an n-hosohedra?

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

    I How do I create a sewing pattern for a spherical lune in 2D from an n-hosohedra?

    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 How do I create a sewing pattern for a spherical lune in 2D from an n-hosohedra?

    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?

    How to Solve a Variation of the Concentrating Salt Tank Problem?

    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...

    How to Solve a Variation of the Concentrating Salt Tank Problem?

    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...

    Why Are Liquid Properties in Steam Tables Labeled with an 'f' Subscript?

    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...

    Why Are Liquid Properties in Steam Tables Labeled with an 'f' Subscript?

    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...

    Triac Heatup: 1000W Draw - Same Rate?

    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...

    My Job as a Mechanical Engineer: Challenges & Benefits

    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...

    Will I have any options if I graduate Physics with a 2.6 gpa?

    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...

    Online ME Masters Degree: Balancing Work and Education - Advice Needed"

    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...

    Programming Languages used in High School Robotics

    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...
