Final answer:
Pascal's discovery regarding fluid power systems, known as Pascal's Law, is relevant in society due to its widespread applications. Examples include hydraulic systems in heavy machinery and medical devices like hydraulic lifts and brakes.
Step-by-step explanation:
Pascal's discovery regarding fluid power systems is known as Pascal's Law or the principle of transmission of fluid-pressure. According to this principle, when an external pressure is applied to a fluid in a container, it is transmitted uniformly in all directions. This discovery has relevance in society as it forms the basis for numerous inventions and applications in various fields.
One example of its relevance is hydraulic systems used in heavy machinery and vehicles. Hydraulic systems use Pascal's Law to transmit and amplify force through fluid pressure. This allows for the lifting, pushing, or moving of heavy objects with ease.
Another example is in the medical field, where Pascal's Law is utilized in devices such as hydraulic lifts for patients or hydraulic brakes in wheelchairs. These devices use fluid pressure to provide smooth and controlled movements, ensuring the safety and comfort of patients.
