### Hydraulic Jack

2T Hydraulic jack designed and animated using

The hydraulic jack is a very useful device for lifting even heavy cars or other loads with the least effort. It is an amplified version of the lever. Here I explain with animations how it works inside.

CCommentsNow, the surface area of the large piston is about thirty times larger than that of the small piston. This where "hydraulic" advantage is obtained. So, the total advantage is 30 x 4, or 120. Lifting a 2,000 pound car requires 17 pounds. If a bottle jack was just a mechanical lever, no fluid would be needed.

I have two such jacks that have failed.

Can you advise what is the most common cause of failure of hydraulic jacks and if they are easy to repair.

Thanks again for any advice.
