What kind of spokes give the strongest wheel strength? I notice most wheels have spokes that are just rods extending radially from the center. Is this generally as strong as it gets, or is this bc of fabrication limitations? What about arched spokes?

Any suggestions or pointers as how I should get started in analyzing the strength of a wheel mathematically?

I want to know if getting good grades while in school would imply that someone will be successful while out in the workforce doing mechanical engineering work. Also assume the person has good communication skills, but is not the type of person that takes things apart and builds things for fun.

I am insulating a cellar and have been given various U values I have to achieve, all companies give their own calculations, but will not show how a result is acheived, which does not give me a choice of materials or combination of materials! only what they will supply. If someone could be unbiased and give me an idea how it's done it would be appreciated
