Hydraulic crane [2]
How it works
We can pick up any small particle with the help of this hydraulic crane. The basic idea behind hydraulics is very simple: Force applied at one end is transmitted to another by a incompressible fluid. Here when we press the piston of one syringe, the piston of another to which it is attached by a pipe, is pushed out by hydraulic pressure. In this way we can control the whole crane.
