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 strength of materials. This subject will also enable the students to continue their further education.

Learning Outcomes:

After undergoing the subject, students will be able to:

• conduct different tests on mild steel
• calculate modulus of elasticity
• analyse and explain stress-strain diagram of mild and HYSD steel
• calculate various forces used in design of structures
• calculate shear force, bending moment for simply supported, cantilever and overhanging beams with concentrated and uniformly distributed loads
• calculate moment of inertia, second moments of inertia, radius of gyration, section modulus for L, T, channel and I sections
• calculate the bending stresses, moment of resistance of simply supported beams
• explain shear stress, stress distribution diagram for rectangular, circular, I,T and L sections
• calculate slope and deflection of determinate structures
• verify forces in a framed structure

5. Determination of maximum deflection and young’s modulus of elasticity in simply supported beam with load at middle third point
6. Verification of forces in a framed structure

Instructional Strategy:

Teachers are expected to give simple exercises involving the applications of various concepts and principles being taught in the subject. Efforts should be made to prepare tutorial sheets on various topics and students should be encouraged/guided to solve tutorial sheets independently. In the practical works, individual students should be given opportunities to do practical work, make observations and draw conclusions. Teachers should also conduct viva examination in which stress should be given on the understanding of basic concepts and principles.

Means of Assessment:

1. Assignments and quiz/class tests
2. Mid-term and end-term written tests
3. Presentations
4. Viva-Voce
