For all other civil 3rd sem syllabus for diploma m scheme tndte you can visit Civil 3rd Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for engineering mechanics is as follows.
Rationale:
This is a basic engineering subject. The purpose of the subject is to impart basic knowledge and skill regarding properties of materials, concept of stresses and strains, bending moment and shear force diagrams, second moment of area, bending and shear stresses, slope and deflection and analysis of trusses. The above knowledge will be useful for designing simple structural components. This subject is very important to develop basic concepts and principles related to structural mechanics. This subject will also enable the students to continue their further education.
Objectives:
On completion of the course, the student will be familiar with:
- The mechanical properties of engineering materials, elastic constants, different types of stresses and strains, the deformation of elastic bodies under simple stresses, the use and principles of composite sections;
- The effects of transverse forces such as shear force and bending moment in beams; determination of SF and BM in simple beams under different loading systems;
- The geometrical properties such as centroid, moment of inertia etc of sections of different shapes;
- Determination of different types of stresses induced in beams and shafts due to bending and twisting moments respectively
- Analysis of perfect frames for vertical loads by analytical as well as graphical methods.
