Statics: Lesson 69 – Moment of Inertia, Composite Shape Method

Statics: Lesson 69 – Moment of Inertia, Composite Shape Method

Master non-symmetric composite shapes in Statics Lesson 69! Professor Jeff Hanson walks you through a complex area moment of inertia problem about a vertical neutral axis. Since the shape is non-symmetrical, you will learn a two-step framework: first, using the centroid table method to calculate the global X-bar distance by subtracting hollow circular and triangular areas; and second, applying the parallel axis theorem. Discover Jeff’s unique “brain rotation hack” to easily switch your base and height definitions for Y-axis calculations without confusion. Avoid common calculator mistakes and ace your civil engineering, mechanical engineering, structural analysis, or FE exam prep!
