COURSE DESCRIPTION

Students learn the concept of stress and strain, elastic constants, principle stress and strain, torsion, shear force and bending moment. They also learn to calculate the deflection of beams by different methods and the concept of strain energy. Students understand different formulas to calculate critical load on columns. After course completion, students will be able to calculate stress, strain, shear force and bending moment for beams, deflection in beams by different methods and critical load on columns.

COURSE OBJECTIVES

1. To know the concept of stress and strain for the calculation of internal forces in the structural member.
2. To know the concept of shear force and bending moment.
3. To calculate deflection in beams, column and trusses.

COURSE OUTCOMES

On completion of this course, the students will be able to

1. Understand the concepts of stress and strain.
2. Analyze shear force, bending moment & torsion for different type of structural members.
3. Calculate deflections in the structural members.
