I've tried looking at this another way. Previously I had assumed a 45o angle for my triangles to the obstacle. Today I started to address the fact that I have a circular wheel to roll over the obstacle. Using the diameter for each tire (front 10.2" and rear 14.5") I obtained the actual angle...
OK here's some rough sketches of the suspension designs, obviously not to scale. The front has changed a little from this drawing in that the spring assembly will not go directly through the strut bar, but through an eye bolt trailing behind it to allow for some rotation. The spring assembly is...
What I'm concerned about is getting springs too weak to adequately react to obstacles up to .05 m (2") at full speed as this will be almost exclusively driven off-road. Of course having springs too stiff is almost as bad. Initially I'd wanted to clear 4" obstacles at full speed, but with just...
I like the dynamite idea... although I'm sure you probably want the bucket in one piece at the end of the experiment. That would also rule out piercing the bottom of the bucket with a spike and letting the water drain out.
The cast of concrete probably wouldn't work. Assuming the alignment is...
An easy way to get the wet bulb temperature is to check the weather at you nearby airport. Every hour (or sooner) they report wind, visibility, cloud coverage, temperature, dewpoint (wet bulb temp), and the altimeter setting. Most airport weather stations have a local phone number you can call...
Hi all. I'm working on building a go kart, and it's been a very long time since my college trig based physics classes. I'm having trouble figuring out the proper stiffness and length of spring to buy for the suspension. In short I need to know the vertical force generated by a wheel and attached...
