Solid Mechanics Fundamentals: Designing a Mechanical Scale

How do engineers design reliable, physical mechanisms that can withstand daily stress and measure weight accurately? Understanding the mechanics of solids is essential for creating safe, functional structures and devices, from simple scales to complex bridges. This course guides you through the foundational physics and engineering principles required to analyze forces, stress, and material behavior in real-world applications. You will transition from understanding basic physical laws to applying them to a practical engineering design challenge: a mechanical luggage scale. Through clear, step-by-step written explanations, you will learn how materials deform under load and how to calculate the structural integrity of your designs. What you'll learn: - Understand the core concepts of stress, strain, and material deformation under load - Analyze forces, moments, and static equilibrium in mechanical systems - Calculate tensile, compressive, and shear stresses in structural components - Apply Hooke's Law and material properties to predict elastic behavior - Design a functional mechanical scale mechanism based on structural requirements - Evaluate safety factors and material limits to prevent structural failure This course begins with essential definitions, foundational mechanics concepts, and material behaviors before moving into structural analysis and practical design calculations. You will read through detailed engineering scenarios and solve structured design problems to solidify your understanding. This course is designed for beginners, aspiring civil or mechanical engineers, and makers with a basic background in high school physics and algebra. No prior engineering experience is required.
