Introduction to Mechanics of Materials and Structural Design

Understanding how materials deform, fracture, and support loads is the foundation of reliable engineering design. This course introduces you to the fundamental principles of material behavior and structural mechanics without requiring advanced prior engineering experience. By studying these comprehensive written lessons, you will learn to analyze forces, calculate stresses, and select the right materials—such as metals, ceramics, and polymers—for various structural applications. You will gain the confidence to evaluate load-bearing components and design structures from a materials-first perspective. What you'll learn: 1. Understand key concepts of continuum stress, strain, and mechanical behavior. 2. Analyze forces in structural trusses and calculate internal loads. 3. Calculate torsion in circular shafts and bending moments in structural beams. 4. Compare the mechanical properties and microstructures of metals, ceramics, and polymers. 5. Apply modern material selection frameworks to choose the best material for specific engineering constraints. 6. Design safe, efficient structural components based on strength and deformation limits. The course starts with foundational definitions of stress, strain, and material classification, before guiding you through practical structural analysis, beam bending, and modern materials selection methodologies. Designed for beginners, aspiring engineers, and design enthusiasts, this course requires no previous background in advanced structural mechanics.
