Re: Undergrad Math Conference Help

May I suggest that you present the derivation for the setup equations for an offset 3link. This would be a setup that would provide equal rear tire loading during launch with any value of driveshaft torque. Some tips: Separate link forces into their horizontal and vertical components. Place the inst...
