Which law was developed in the 1600s to describe that any force applied to a confined fluid is transmitted equally in all directions, regardless of the shape of the container?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Pascal's Law.
The law developed in the 1600s that describes how force applied to a confined fluid is transmitted equally in all directions is known as Pascal’s Law. Formulated by Blaise Pascal, this principle states that when pressure is applied to a confined incompressible fluid, the pressure change occurs throughout the entire fluid equally. This law is fundamental to fluid mechanics and is the working principle behind hydraulic systems, such as hydraulic lifts and brakes, which multiply force effectively in machines.
