A hydraulic press shear operates on the principle of Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished throughout the fluid. This means that a small force applied to a smaller piston can be amplified to produce a much larger force on a larger piston. In the case of shears, hydraulic cylinders generate immense pressure that allows the blades of the shear to cut through materials effectively.
