Car Jack Torque Calculation - 100kg - Physics Forums
2007年3月1日 · What is car jack torque calculation and why is it important? Car jack torque calculation is the process of determining the amount of force or torque needed to lift a 100kg car with a car jack. This calculation is important because it ensures that the car jack is strong enough to lift the weight of the car without causing any damage or accidents.

2004年11月2日 · P_{1} and P_{2} are the power of the car jack in the first and second scenarios, and t_{1} and t_{2} are the times it takes for the car to be lifted in the first and second scenarios.In summary, a car jack is used to lift a quarter of the weight of a 1200kg car 20 cm in 20s. To calculate the power of the car jack, the formula P = mgh/t is used.
