Animate the belt

- So now that we have the pulleys in place, we can use their motion to determine the motion of the belt. Now just like with everything else, it is going to be a ratio. So when this rotates once, the belt will move a certain distance. But what is that distance? Well, so what we need to do here is compare the actual length of the belt to the circumference of the pulley. So this is the pulley that's driving the system. So, its diameter I determine here as 5.3. So we can actually do just a little bit of math to find out what the physical distance is around the edge. And that's really simple trigonometry. So all we need to do is type in this number 5.3 times pi which is what, 3.14, or you can go 3.1415, or however much, however many decimal points you want. So that physical distance around it is 16.642. So I'm going to go ahead and plug that into my memory here so I'm going to remember that. And then what we need to do is figure out the length of this belt. Well, we've got a curve here…
