Core Principles & Analysis

• The law was established by French mathematician Blaise Pascal in 1653 and published in 1663.
• Pascal's principle underlies the operation of the hydraulic press, where force can be multiplied in principle by any amount.
• If the right-hand tube is made 50 times wider, a 1 N load on the left piston produces a 50 N upward force on the right.
