SUMMARY
The maximum load a scissor jack must support when lifting a 6000 lb car varies based on the car's center of gravity and the jacking point. When the car leans on the back wheels, the maximum force exerted on the jack is 4800 lb, while leaning on the side wheels results in a maximum force of 3000 lb. The calculations involve taking moments about the tires, with specific distances from the center of gravity to the jacking points influencing the results. Understanding the car's geometry and weight distribution is crucial for accurate calculations.
