Area Moment of Inertia Calculations

The area moment of inertia, also known as the second moment of area, is a geometric property that measures the stiffness of a two-dimensional shape or object. It describes the distribution of points within an area relative to an arbitrary axis, and is crucial for understanding how the area resists bending or deformation. In this …

Drag Coefficient Units

When a solid body moves relative to the viscous fluid surrounding it, a net force is exerted on the body. The magnitude of this force is influenced by various factors, including the relative velocity, the shape and size of the body, and the properties of the fluid. This article specifically examines the drag coefficient, which …
