OK, here's what I've come up with. I can treat the interaction with the tire and the roller like a ramp. I can take my known hydraulic pushing force (2651 lbs) and multiply it by the SIN Θ of the initial angle where the tire touches the roller, right?
2651 * SIN 30° = 1325 lbs or force acting on the tire in the vertical direction at the beginning. As the hydraulic continues to push the roller to the left, the tangential angle gets smaller and force acting on lifting the tire goes down, right? 2651 * SIN 10° = 460 lbs of force lifting the tire. Then if the roller is completely under the tire there is no lifting resultant force (2651 * SIN 0° = 0 lbs).
So now I'm stuck on the variable of the weight of the car (tire). If I need to lift 2000 lbs, did my equation above say I can only lift 1325 lbs? What about the roller on the other side of the tire, is it helping the same way as the roller that is being moved hydraulically? So do I have 2650 pounds of lifting force at the beginning (the resultant force on both rollers added together)?
