Ch 7: Equilibrium and Elasticity: Help and Review

About This Chapter

The Equilibrium and Elasticity chapter of this Physics 101: Help and Review course is the simplest way to master equilibrium and elasticity. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure you learn the essentials of equilibrium and elasticity.

Who's It For?

Anyone who needs help learning or mastering equilibrium and elasticity material will benefit from the lessons in this chapter. There is no faster or easier way to learn about equilibrium and elasticity. Among those who would benefit are:

  • Students who have fallen behind in understanding elastic modulus and types of equilibrium
  • Students who struggle with learning disabilities or learning differences, including autism and ADHD
  • Students who prefer multiple ways of learning science (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who need an efficient way to learn about equilibrium and elasticity
  • Students who struggle to understand their teachers
  • Students who attend schools without extra science learning resources

How It Works

  • Find videos in our course that cover what you need to learn or review.
  • Press play and watch the video lesson.
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with short quizzes.
  • Verify you're ready by completing the Equilibrium and Elasticity chapter exam.

Why It Works

  • Study Efficiently: Skip what you know, review what you don't.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Use the Equilibrium and Elasticity chapter exam to be prepared.
  • Get Extra Support: Ask our subject-matter experts any equilibrium and elasticity question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

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.

What is a Truss Bridge? - Designs & Definition

7. What is a Truss Bridge? - Designs & Definition

In this experiment, you'll be studying the effect of structural arrangement of supports in truss bridges. Through this experiment, you'll learn about different variations of truss bridges and how they change the amount of weight a bridge can support.
