Hint:A jack is a mechanical lifting device that may be used to produce massive forces or raise large weights. For raising large machinery, a mechanical jack uses a screw thread. Hydraulic power is used by a hydraulic jack. A car jack, floor jack, or garage jack is the most popular type, which elevates automobiles so that maintenance may be conducted. The maximum lifting capability of jacks is frequently specified (for example, 1.5 tons or 3 tons). Many tonnes of load may be supported by industrial jacks.
Complete answer:
Hydraulic jacks are very helpful mechanical devices that are used to raise big objects. These jacks can raise more weight over longer distances thanks to hydraulics. In the automotive, industrial, and construction industries, hydraulic jacks are extensively used. Hydraulic jacks are divided into two categories: bottle jacks and floor jacks.
The bottle jack, as the name indicates, is portable and has a vertical piston with a weight-bearing pad on top. Bottle jacks are particularly handy for changing wheels and are regularly used with cars. The jack is placed beneath the automobile at the proper height for elevating it, and then the jack is pumped up using a detachable lever, elevating the vehicle to allow the wheel to be replaced.
The vertical action for raising is provided by horizontal pistons and a long arm on a floor jack. Floor jacks are commonly found in garages and have wheels or castors. These jacks can raise a lot more weight than bottle jacks.
Hence option B is correct.
Note:Hydraulic jacks function by forcing hydraulic fluid into the jack's cylinder through a pump plunger. The hydraulic fluid is taken from the reservoir into the pump chamber when the plunger is pulled back, and the hydraulic fluid is pumped back into the cylinder when the plunger is pushed forward. The movement of the fluid increases the pressure in the cylinder, causing the hydraulic jack to function.
