Scissor Jack load

  1. 1. The problem statement, all variables and given/known data

    I have to determine the max load a scissor jack must support when lifting a 6000lb car. I know where the center of gravity is acting and the potential locations (distances from the center of gravity) the car will be jacked up. I know the max force is less than 6000 lb.

    The attached document shows the geometry of the car.

    2. Relevant equations

    3. The attempt at a solution

    I tried taking the moments about one of the tires and setting them equal to zero to solve for the max force at each location, but I know I'm doing something wrong.
