Basics of Equilibrium in Engineering Mechanics


  • Basic Physics


This is the basic course on the chapter - Equilibrium.

The contents of this course are:

1) Definition of Equilibrium - In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero.

2) Free Body Diagram - Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.

3) Lami's Theorem - When three forces acting at a point are in equilibrium, then each force is proportional to the sine of the angle between the other two forces.

4) Conditions of Equilibrium - ∑Fx=0, ∑Fy=0, translational equilibrium, ∑M=0, rotational equilibrium. The above three equations should be satisfied for 2D Equilibrium of the body. So in total there are three conditions of equilibrium for two dimensional cases and six conditions of equilibrium for three dimensional cases.

5) Problem on Equilibrium

6) Types of supports - i) Simple support (sliding support and roller support), ii) Hinge support or pin support, iii) Fixed support

7) Types of beams - i) Simply supported beam, ii) Cantilever beam, iii) Fixed beam, iv) Continuous beam, v) Overhanging beam

8) Types of loading - i) Concentrated load or Point load, ii) Uniformly Distributed Load (U. D. L.) or Rectangular Loading, iii) Uniformly Varying Load (U. V. L.) or Triangular Loading.

Hello there. I am currently working as an Assistant Professor in Karmaveer Kakasaheb Wagh Institute of Engineering Education and Research, Nashik, Maharashtra, India. Previously I was working with a consultancy firm as a Structural Design Engineer in Industry for 3 years and having teaching experience during Masters too.

I have taught Engineering Mechanics to first year students since last 5 years.
