This is a student project. I have two gears, one is fixed and the other turns around it, there is a slot on the moving gear holding a slider, the slider changes position as the second gear turns, the whole system is hold in upright position. Forces in effect are gravity, the weight of the components, and traction. i want to run two analyses to check the stability of the system, one without traction and the other considers it... the studies may use variables for weights... we can also assume starting point at fixed speed at zero degree. it is better if you can use Pro Engineer. Please see the attachment to get visual about the system. P.s: To balance the system i added third gear on 180 degrees from moving gear, so they are symmetrical about the fixed gear, and added second slider, and extended the two bars to accommodate the new gear and slider. this way the system is balanced and the slider is the focus point. I am okay with adequate theoretical solving and diagrams.

Placement of a high torque electric motor longitudinally behind rear wheels of vehicle or behind center of gravity in plane. The motor has a gear reduction unit and is attached to frame. It has sensors from pitch, yaw, air speed and altitude, or brakes, transmission and vehicle speed and is computer controlled to give pulses clockwise and counterclockwise to turn the vehicle or plane. As motor turns clockwise the force is to the right on rear of frame and alternate force in front is to left and vice versa. It is a augmentative steering control and in planes can also be used when loss of standard steering occurs.
