    Tricycle physics

    Are you able to go a little more in depth with this? Calculating the forces and the torque is easy enough, and I found a formula for moment of inertia so I have that. (I assume the Z axis is on the midpoint between the fork wheels?), but then I am completely lost. I found a formula for angular velocity using torque and inertia, but I don't know what to do with it. I don't know what integration is, do you know of a good resource, or what I need to learn first? I've tried watching a few videos on youtube about it, but I don't understand at all what they are talking about.

    Tricycle physics

    Thank you very much! Wasnt sure if my question made enough sense to get and answer, but you gave me exactly what I was looking for! I dont fully understand a few things here, but it's a great starting point for me to go learn some more stuff. I'll report back if I have any more questions. Thanks again!

    Tricycle physics

    EDIT: I found the resources I need after posting this on: Hello all, I am trying to workout how a pallet jack (esentially a tricycle) would travel. I'm looking at top-down 2D here. My current setup is that I have a handle fixed to a point on the jack body, with an angle independent of the jacks body. The jack body then has an angle, and as the jack moves forward (as in you pull the jack along), it's angle would converge by some constant on the handle angle. When pushing the pallet jack it would instead diverge by some constant until the handle hits some maximum angle and then the jack would spin on the spot. This works OK, but it there are some mistakes. When the handle is 90 degrees from the jack body, it should spin with the center of rotation being exactly between the two fork wheels. Using this method I couldn't figure out how to rotate about the correct spot. I thought about just having edge cases be handled different, but I was hoping someone knew of a better all encompassing solution. Either using friction/drag and other physics concepts, or just using geometry. I tried using geometry and trigonometry to calculate some circle that the jack should be travelling along but I haven't had any luck. Am I over complicating this? I'm not search how to search for "physics of pulling an object behind you with drag", so I haven't been able to find any resources. EDIT: Finally found something on google (now realizing that the same problem applies to 4 wheeled vehicles), I reached this same sort of solution, but I am stuck on how the jack moves along the circle: Thanks for reading.
