 Hello and welcome back to another episode of Physics Partner. In today's video we are going to uncover the secrets behind how hydraulic car lifters work and explore the physics that makes it all possible. Hydraulic car lifters are a crucial tool in automotive workshops and garages alloying mechanics to effortlessly lift vehicles for maintenance and repairs. And have you ever wondered how this marvel of engineering actually works? Well, let's break it down for you. At the heart of a hydraulic car lifter is a hydraulic pump that is connected to a series of hydraulic cylinders. These cylinders contain hydraulic fluid, typically oil, which is pushed through them by the pump. Now let's dive into the physics behind hydraulic car lifters. The principle that makes hydraulic systems work in Pascal law, which states that when pressure is applied to a confined fluid, it is transmitted undiminished in every direction. In the case of a car lifter, when the hydraulic pump applies pressure to the fluid in the cylinders, it creates a force that is transmitted to a piston at the other end of the cylinder. This force is then used to lift the vehicle off the ground. To understand this better, imagine a small piston on one side of the cylinder being pushed down by the hydraulic fluid. This creates a force that is transmitted through the fluid to a larger piston on the other side of the cylinder, lifting the vehicle as a result. The beauty of hydraulic car lifters lies in their ability to generate a significant amount of lifting force with a relatively small input force, thanks to the mechanical advantage provided by the different size of the pistons. And there you have it. The intricate workings and physics behind hydraulic car lifters.
