A hydraulic jack is a mechanical lifting device that uses liquid pressure to raise heavy loads, such as vehicles or machinery. It consists of key parts including a cylinder, piston, pump handle, oil reservoir, and valves, and is typically made from strong steel. It works based on the principle that pressure applied to a fluid is transmitted equally in all directions.
Operation:
A hydraulic jack works by pumping hydraulic oil into a cylinder using a handle, which creates pressure that pushes a piston upward. As the piston rises, it lifts the load placed on the jack. When the release valve is opened, the oil flows back into the reservoir, causing the piston to lower and the load to descend smoothly.
