Is a car jack a simple machine?

Do simple machines reduce the amount of work?
By simple machines, I assume you mean machines powered by muscle but using leverage such as levers, screws, block and tackle devices. Is that what you mean? If so, these devices increase something called "mechanical advantage". Start with levers. The usefulness of a lever depends on where the fulcrum is placed. If the fulcrum is in the centre of a lever such as with a see-saw, there is no mechanical advantage at either end. That's why kids of similar weights can suspend the kid on the other end of the see-saw up in the air just to be rascals. Now if the fulcrum is closer to one end than to the other, the person farther from the fulcrum can exert more force than the person closer to the fulcrum. Think of a crow bar. One inserts an inch or two of the bar at the point where one wants to apply force. Pushing on the other end of the bar (perhaps two, three, four feet away) exerts a lot of force at the other end. The same effect allows you to lift a car with a jack. You push down a foot on the jack handle and the jack platform rises perhaps half an inch.
Is screw jack reversible machine?
Screw jack is a non reversible machine,as it does not return to its original position even after the load is applied
Who manufactures the gentle jack jackhammer?
Currently no one on the market is producing the "gentle jack". Dennis Lee, a con artist who also sells shares in a perpetual energy machine concept, was also selling plans in the "gentle jack". Currently the original inventor is working with a manufacturing company out of North Dakota and their engineering team to produce the hammer.

How big of a floor jack do you need for a dodge ram 1500?
My scissor jack collapsed under the weight and many hydraulic jacks can't get enough height so I place some blocks under the jack before pumping it. My estimate is get a jack that can carry at least 3500 lbs and has a higher range of motion. The scissor jack works the height but need a heavy duty one.
What are two or more simple machines called?
There are six simple machines: Inclined Plane Wedge Screw Pulley Wheel Lever The two classes of simple machines are: 1. The simple machines that deal with vector quantities like velocity and force (the inclined plane, the wedge and the screw). 2. The simple machines that deal with torque (the force to rotate an object around an axis, pivot, etc.) like the pulley, the wheel, the lever. You would think a screw falls into the torque class, but it's classified as a helical inclined plane.
