2. Course Description:
• This course requires good understanding of fundamental concepts in Engineering
Mechanics.
• To understand the strength aspects and physical performance of the structures
• To understand the concepts of internal forces, deformations, stresses and strains, elasticity,
plasticity, strain energy, etc.,
• These concepts help us to design the structures as well as the Mechanical systems.
• It also helps to develop analytical techniques to solve the linear stress/strain problems

3. Course Objectives:
• To gain the understandings of the concepts of stress and strains, their relationships within the
linear elastic domain.
• To understand the applications of fundamental principles of equilibrium, method of sections,
force-deformations, principle of superposition in linear elastic zone to solve the problem like
bars, rods, beams, etc

4. Course Outcomes:
Upon completion of the course student should be able to:
• Analyze and design structural members subjected to tension, compression, torsion, bending and
combined stresses using the fundamental concepts of stress, strain and elastic behavior of
materials.
• Utilize appropriate materials in design considering engineering properties, sustainability, cost
and weight.
• Perform engineering work in accordance with ethical and economic constraints related to the
design of structures and machine parts.
