About This Chapter
Equilibrium & Elasticity - Chapter Summary
In this helpful chapter, our instructors present topics related to equilibrium and elasticity. As a part of your study, you'll review the difference between rotational equilibrium and translational equilibrium. This chapter is designed to help you:
- Understand center of gravity and stability
- Detail the applications and problem-solving methods for statics
- Differentiate between inclined plane, pulley and lever simple machines
- Identify tensile and compressive stress and strain equations
- Make calculations using shear and bulk stress and strain equations
- Outline the equations relating to Young's Modulus
- Define strain energy
We make even the most complicated topics easy-to-understand with our clearly written and easy-to-follow learning tools. You can simply navigate our video lessons using the video tabs feature, so you don't need to watch the entire lesson to get to one topic. As a test prep exercise, the lesson quizzes and chapter test are a great way to check to make sure you're on the right track.
1. Equilibrium: Translational & Rotational
Learn about the requirements for an object to be under translational or rotational equilibrium. Then work through a couple example problems that show how we can use translational and rotational equilibrium to find the forces acting on an object.
2. Stability & Center of Gravity
Discover what stability means and why center of gravity is so important to understanding it. Then learn about the different states of stability and how to tell the difference between them.
3. Statics Problem-Solving Methods & Applications
Find out exactly what requirements need to be satisfied for a physics problem to be classified as a statics problem. Then learn the steps you take to solve these statics problems.
4. Simple Machines: Lever, Inclined Plane & Pulley
Discover what a simple machine is and how it operates. Then learn about the mechanical advantages various simple machines such as levers, inclined planes and pulleys give us.
5. Tensile and Compressive Stress and Strain Equations
Discover what tensile and compressive stress and strain are, and how they relate to each other. Then find out how we can use stress and strain to learn more about a material's elastic properties.
6. Shear and Bulk Stress and Strain Equations
Discover how to tell when an object is experiencing normal, shear, and bulk stress and strain in this lesson. Then, learn about the basic formulas we use to find shear and bulk stresses, strains, and moduli.
7. Young's Modulus: Definition & Equations
Young's modulus is a material property that tells you how stiff or stretchy a material is. In this lesson, learn how to calculate Young's modulus and what it can tell you about the material.
8. Strain Energy: Definition & Calculation
Whenever you push or pull on a deformable object like a rubber band or spring, you transfer some energy to it. This is known as strain energy. Learn how to calculate it in this lesson!
