Engineering Mechanics: Fundamentals of Stress, Strain, and Structures

Understanding how external forces affect materials and structures is the foundation of reliable engineering design. This course equips you with the analytical tools necessary to predict structural behavior and prevent catastrophic failures. By the end of this course, you will be able to analyze fundamental structural components under various loads, calculate internal stresses and strains, and determine appropriate material selection based on physical properties and established failure criteria. What you'll learn: * Understand the relationship between external forces and internal stresses, including normal and shear stresses. * Apply static equilibrium principles to determine reactions and internal forces (axial, shear, moment) in beams and trusses. * Calculate strain, deflection, and deformation in structural members subjected to axial, torsional, and bending loads. * Master key material properties (elastic modulus, yield strength) and critical failure theories used in engineering practice. * Practice solving analytical problems using fundamental principles that underpin modern computational structural analysis methods. * Analyze combined loading scenarios and introduce the concept of stress transformation using Mohr's circle. The course begins by defining key terminology and reviewing essential concepts of static equilibrium, then progresses systematically through the analysis of stress and strain, torsion, bending, and deflection. Practical exercises reinforce the analytical concepts required for safe and effective design. This course is designed for absolute beginners interested in civil, mechanical, or structural engineering. No prior knowledge of mechanics is required, only basic algebra skills.
