Basic Concepts of Mechanics of Materials for Machine Design

Course details

Mechanics of Materials is the primary course for  mechanical engineering and is used in the design of structures and machines.

A thorough understanding of the foundational concepts of the subject is important to for mechanical design whether it be designing a single structure which has to take loads or whether it is designing an elaborate Transmission systems which is undergoing dynamic loading conditions.  Mechanics of materials concepts are cornerstone of any type of mechanical design .

In this course we will be covering the following concepts :

1. Introduction to Machine design - What is nature of machine design ? What does it include ? What is the engineering design process?

2. Importance of analysis of strength and difference between strength and stress

3. Essential basics of engineering statics - Method of statics, Free body diagrams, Force equilibrium , types of joints

4. primary types of loading- Normal and shear

5. What is Bearing stress

6. Explanation of Stress and strain relations with Tensile test and its inferences along with definitions of tensile strength , yield strength .

7. Hookes law

8. Shear Stress strain relations and Shear stress in Shafts undergoing action of torque- Torsion.

9. What is Poissons' Ratio

10. Analysis of Axially loaded member and what is stress concentration

11. Analysis of Stress in Oblique plane for axially loaded member

12. What is Pure bending ? Derivation of governing equations .

13. What is Area moment of Inertia

14. Analysis of Beams and deriving shear force and Bending moment diagrams

15. Two Plane bending in shafts

16. Stress concentration in Bending

17. Analysis of Shaft in torsion and derivation of Governing equations

18. Solid vs Hollow shafts

19. Stress concentration in Shafts

20. Multi axial Loading , Dilatation and Bulk Modulus

21. State of Stress and Stress transformations

22. Analysis of Thin walled pressure vessels

23. What is Principal stress and derivation of Mohrs' Circle

24. Comparison of plane of Principal stress and Maximum Shear

The course covers the Theoretical basics required to design standard  elements in structures and machines.

Aim of the course is to build a strong well rooted understanding of the concepts rather than just mere application of formulae.

A good engineer knows the underlying assumptions of each formula they use in application and hence knowing the mathematical back ground is very important for effective design.
