An airbag, also known as a Supplementary/Secondary Restraint System (SRS) or as an Air Cushion Restraint System (ACRS), is a flexible membrane or envelope, inflatable to contain air or some other gas. Air bags are most commonly used for cushioning, in particular after very rapid inflation in the case of an automobile collision.

HYDRAULICS |
|
Hydraulics is a branch of science and engineering concerned with the mechanical properties of liquids. It is part of the more general discipline of fluid power. The word "hydraulics" comes from the Greek word ὑδϱαυλικός (hydraulikos) which in turn comes from ὕδϱαυλος meaning water organ which in turn comes from ὕδωϱ (water) and αὐλός (pipe). The earliest masters of this art were Hero of Alexandria and Ctesibius. The ancient engineers however focused on sacral and novelty uses of hydraulics, rather than practical applications. One of the founders of modern hydraulics was Benedetto Castelli, a student of Galileo Galilei.

LIFTING EQUIPMENT |
|
A mechanical jack is a device which lifts heavy equipment. The most common form is a car jack which lifts vehicles so that maintenance can be performed. Car jacks usually use mechanical advantage to allow a human to lift a vehicle. More powerful jacks use hydraulic power to provide more lift over greater distances. A mechanical jack is called a Floor Jack or a Garage Jack. A three ton jack is good around the Shop or the DIYer's Garage. The higher the jack's ton rating the better, a three ton jack will raise an automotive more than the 2 1/2 jack.
