For all other robotics 4th sem syllabus for diploma m scheme tndte you can visit Robotics 4th Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for mechanics of materials is as follows.
Rationale:
Mechanical Engineers must have knowledge about mechanical properties of material, deformation of material subjected to axial load and shear. This will provide adequate knowledge to work as a design engineer.
Objectives:
- Define various mechanical properties of materials.
- Calculate the deformation of materials, which are subjected to axial Load and shear
- Determine the moment of inertias of various section used in the industry.
- Estimate the stresses used in thin cylinder under internal pressure.
- Draw the graphical representation of shear force and bending moment of the Beam subjected to different Load.
- Construct SFD and BMD.
- Calculate the power transmitted by the solid & hollow shafts.
- Distinguish different types of spring and their applications.
- Define Types of Friction.
