Math RAMP Video Topics
 

I'm going to make some more videos really soon, and the first ones I want to do are a bunch on different calculations and trends that we use a lot in design that others might not know about.

So please, reply with any and all requests in terms of any math or calculations (or trends... like what makes a gusset strong? How do bellypans work? what makes thinwall tubing more efficient?) that you would like covered.

Thanks!

Speeds and feeds.....

OH. You do NOT want me to do that, I'd get others on 973. My strategy for running the router is use the same numbers that didn't break the cutter last time. I don't have the patience for such things :rolleyes:

I'll see if I can get a cameo video for that.

As far as my pretend machine side goes, I generally stick to Gwizard..... and a little guess and check. :rolleyes:

What happens in a pushing match, and which robot will win? What math is involved with forming the profile of a tooth? How can we model the acceleration of an arm or elevator? What's the correct speed and power to run an intake at? What's the most efficient way to lighten (a gearbox, a gusset, a bellypan, a robot, take your pick)? How thin material you can "get away with" (in tubing, gussets, gearboxes, gears)? What's the best way to model inefficiencies due to friction and calculate frictional forces/losses in FRC (in gearboxes)?

Sorry for the huge list. I'll probably think of more stuff later tonight :)

+1.

Also, how do you approach flywheel design? How do you go about maximizing the moment of inertia of a flywheel while maintaining reasonable spin-up time?

FEA.....
not really math but can you do I video on design tables, parts library, and blocks.

How do you calculate and design around flexibility of irregularly shaped composite materials?

Re: Math RAMP Video Topics
 

Could you do a video on the drawbacks of FEA?

Some basic strength-of-materials principles, particularly on how different geometries (tube, channel, angle) handle various loads and the most optimal places to remove material from these members.

Basic first-order gear strength calculations (thinking Lewis numbers more than AGMA formulas) in order to get a rough idea how to size a system.

Work-Energy for everything.

If you do anything to model strength for over-the-bumper things (or resilience / toughness for compliant materials) seeing how you do that would be really useful. I think a lot of teams are looking to put more emphasis on robust OTB systems after this game.

Re: Math RAMP Video Topics
 

I would be very interested in a video about scouting (quantitative data) and it's application to match strategy.

Re: Math RAMP Video Topics
 

I'm actually interested in the opposite (as well). What kind of qualitative data do you collect, and how do you use it when making pick lists/match strategies?

How large should safety factors be for different things? Torque in a winch, belt tensile strength, press fit strength, superstructure strength, etc?
