One of the things I think you're having problems with is your free body diagram. Free body diagrams are only meant to view a single body. I think you may be confusing the equal and opposite forces at work with some idea that they may be canceling each other out. They are not. In the end, the...

You just gave the force of the chain acting on the wheel. How are you still confused about it? The chain simply transmits the linear force from one gear to the other. The radius of the gear about its fixed axis makes it a torque applied to the wheel, and the radius of the wheel changes it...

The tire exerts a force onto the ground equal to 50N. It can also be said that the ground exerts a 50N force on the tire. If this is the only force acting on the bike in the x-direction, then the bike will accelerate in the x-direction. If not, then you must sum all of the forces acting in...

All I could find on google or elsewhere on the internet regarding angular velocity, acceleration, and the like were kinetic energy formulas like 1/2*mv^2, and others that substituted I for the mass, and angular velocity for v. I also found several integration formulas, that I didn't try to use...

BTW, here are couple of shots from the model inputs and outputs. I've scaled my car, and put it on the dyno. Then I took it to the track two days ago and ran a: 60': 2.2422 1/4 ET: 13.35s 1/4 Trap: 105.49mph

I'm building an excel dragstrip model. I already have a working model that incorporates force exerted at the rear tires, force of drag, and force of rolling resistance. Now, I want to take into account the linear force that acts on the front tires that is required to accelerate them. There is...
