👉 A requiring fluid, also known as a lubricant or a viscous fluid, is a substance that reduces friction between surfaces in motion or at rest. It plays a crucial role in various mechanical systems by minimizing wear and tear, ensuring smooth operation, and extending the lifespan of moving parts. Common examples include oils, greases, and hydraulic fluids, each designed to perform under specific conditions and pressures. These fluids are essential in machinery, engines, and other mechanical devices to maintain optimal performance and efficiency.
