Description

This course is the second part of the lecture series of Strength of Materials subject. It takes you through various topics like Centre of Gravity(C.G.) & Moment of Inertia(M.I.), Strain Energy, Deflection of Beams and Theory of Torsion. Various numerical are solved to explain various concepts and their applications. Basic Mathematics and Solid Mechanics are the requirement for understanding of this subject.

We start with introduction to (C.G.) and Moment of Inertia(M.I.) and then solve numericals based on C.G. and M.I.. Concepts like centroid, centre of gravity, radius of gyration, moment of inertia, polar modulus, section modulus, mass moment of inertia, area moment of inertia, parallel axis theorem and perpendicular axis theorem are explained here.

Further, we move to the concept of Strain Energy. Three cases are discussed here- gradually applied load, suddenly applied load and suddenly applied load with impact. Strain energy for all these cases are discussed and also strain energy in composite and compound bars.

Third section Deflection of Beams is explained. Flexural formula is derived and Macaulay's method is discussed which is then used for solving numericals for calculation of slope and deflection of beams under various loading conditions.

Lastly we study about theory of torsion and derive torsional formula. Numericals are solved which is about designing shafts and analyzing if the design is safe for practical use. Concept of statically indeterminate shafts is discussed and numericals are solved based on it.

Who this course is for:

  • Diploma in Mechanical/Civil/Automobile/Production Engineering Students
  • Competitive Exam students like GATE, IES etc.
  • Degree students of Mechanical/Automobile/Civil/Production Engineering Students
