Ch 8: Equilibrium and Elasticity

About This Chapter

Watch video lessons and learn about the concepts of equilibrium and elasticity. The quizzes that follow each lesson can help you gauge your comprehension of the materials.

Equilibrium and Elasticity - Chapter Summary and Learning Objectives

Equilibrium and elasticity are key introductory concepts in physics. In this series of lessons, you'll learn about different types of equilibrium and their characteristics. You'll then be able to apply this knowledge to understanding how simple machines work, how factors like gravity affect equilibrium and elasticity and how to solve problems where you'll need to measure equilibrium and elasticity. In these lessons, you'll learn things like:

  • Types of equilibrium
  • Types of stability
  • Types of simple machines
  • How to solve equations that include calculating equilibrium and elasticity

Equilibrium: Translational & Rotational

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.

Stability & Center of Gravity

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.

Statics Problem-Solving Methods & Applications

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.

Simple Machines: Lever, Inclined Plane & Pulley

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.

Tensile and Compressive Stress and Strain Equations

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.

Shear and Bulk Stress and Strain Equations

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.
