This is probably obvious to the folks good with math but it's been 40 years since school for me and I was never a math wizard.
I basically need a formula to figure out the picture below.
3000 lbs pushing down on an incline of 18.1 degrees - I need to know how much force would be moving the triangle to the right assuming no friction between the bottom and whatever it would be setting on
or
3000 lbs of force toward (and pinned) to the center rolling around an 8" fixed wheel offset by 2 inches in the center. - how much sideways force would be generated? Either one has to roll 12.56 inches and move 4" toward the center if that makes any difference.
The pic on the right is actually what I'm working with but I figured the other would give me an average
Is there any simple formula I can plug the numbers into to get a torque or ft lb push value?
What I'm trying to figure out is the output torque on a simple hot/cold water motor I want to build. It will run off the psi differential between a cold water tank and a hot water tank sides using either propane or freon to pressurize some auto air springs mounted in a wheel frame. The tank is split with simple plastic hinges that allow the bottles in the water to switch from side to side as the wheel rotates around the center axle. The air springs are made from nitrile rubber which is pretty much immune to either type of gas I could use. The hot water will come from a solar panel and the cold from our well if possible. I want to be able to water my wife's garden using a trickle system by driving a small piston pump with it and possibly spin a small wind turbine type home made alternator if it will create enough torque once geared up to about 500 rpm. The output will be taken from a #50 or #60 chain gear on the top cover
The picture below is a top down view. The axle will be fixed to a very heavy metal frame supporting the circular water tank and motor wheel itself at both top and bottom of the axle. The top and bottom covers not shown in the pic will have the bearings for the wheel. It rotates around the fixed axle and offset wheel in the center. 3000lbs force will be the maximum allowed to each air spring. I'm need to find out the torque for one and I can figure out the rest. Yea, this thing is going to be a bit heavy as that outside frame is probably going to be 7/16" thick 8" wide steel strips bolted together with the covers at least 1/4" thick...There will be a lot of force on that axle/offset wheel once it gets going and it's got to be a strong frame...It will probably only turn about 2-3 rpm max due to the heat transfer time from the water to the little paintball CO2 bottles with the gas in them that will be setting in the water tank.
