I need to know how much stress a manual hydraulic car jack has while holding a 4000 lb load?

I suggest hiring a professional engineer.

Otherwise, you'll need a lot more detail on the specifics of the car jack.

faiz513: For which component in the hydraulic car jack do you need to know the stress? And what is the diameter and cross-sectional area of that component?

i need to know the stress the hydraulic piston, which has a diameter of about 1 inch is a able to withstand?

The piston is not going to be the part that fails when the jack is overstressed. Which part do you think will fail first, and how will it fail... ?

Bit of an elementary question really. Stress is force/unit area.

Unless you want a more specific and/or useful answer more info is needed.
