Mechanics Of Materials Part 1

The study of stress, strain, torsion and bending

What you'll learn

Chapter 1 - Calculate internal loadings, normal stress, shear stress and allowable stresses

Chapter 2 - Determine normal and shear strains caused by external loads

Chapter 3 - Understand stress-strain diagrams and Poisson's ratio

Chapter 4 - Calculate elastic deformation due to axial loads, thermal stresses and statically indeterminate systems

Chapter 5 - Find angle of twist and stresses due to torsional loadings

Chapter 6 - Understand the concepts of the flexure formulas, drawing shear and moment diagrams, and bending stresses

Requirements

Students must have already completed a Statics course. We will be drawing free body diagrams and using the concepts of equilibrium and method of sections.

The calculus concepts of derivatives and integrals are also needed.

Description

Mechanics of Materials is the class that follows Statics. It uses many of the concepts learned in Statics like equilibrium, moments, method of sections, and free body diagrams. The difference between the two courses is that in Statics you study the external loadings. In Mechanics of Materials, we'll study how external loadings affect bodies internally.We'll look at things like shear stress and strain, how temperature causes deformation, torsion (twisting), bending and more. Gone are the days of rigid bodies that don't change shape. Now things will be getting longer / shorter, twisting, bending and changing shape.Here's what you get with the course:1. 15.5 + hours of on-demand videos featuring easy-to-follow lectures and problem-solving tips2. Fully worked examples in a range of difficulty levels3. Homework problems for you to apply the knowledge learned. Solutions are included.4. We will cover most sections in Chapters 1-6 of the widely-used Mechanics of Materials textbook by Hibbeler.5. Downloadable outline of notes to help you follow along with me in the lectures6. Downloadable equation sheet that contains all the important equations covered in class7. An experienced instructor with 20+ years of university teaching experience & 8 years of industry experienceThis is a fundamental engineering course that is a must-have for any engineering student.  Enroll today!
