The Efficient Engineer - Fluid Mechanics - Understanding Aerodynamic Drag 12012021

Drag and lift are the forces which act on a body moving through a fluid, or on a stationary object in a flowing fluid. We call these aerodynamic forces (if the fluid is a gas) or hydrodynamic forces (if the fluid is a liquid). This video focuses on drag force and the two main causes of drag - pressure distribution around the object, and shear stresses acting on the object, which are most significant for streamlined bodies
