# CV1011 Mechanics of Materials

[Lectures: 39 hrs; Tutorials: 13 hrs; Lab: 0 hrs; Academic Units: 4.0]

Learning Objective

The objective is to equip the students with the basic understanding of force vectors and their operations, force equilibrium, stresses and strains of a body when the body is subjected to external loads. The subjects covered in this course provide essential technical basis for the analysis and design of civil structures.

Course Content

This course covers the basic topics of mechanics of materials. The principal topics are force vectors, equilibrium of rigid body, stress and strain, mechanical properties of materials, analysis and design of structural members subjected to tension, compression, torsion, bending and shear, the transformation of stress (strain) components, and the stability of columns.

Course Outline

 S/N Topic 1 Force vectors 2 Force system resultants 3 Equilibrium of a rigid body 4 Geometric properties and distributed loadings 5 Internal loadings 6 Stress and strain 7 Mechanical Properties of Materials 8 Axial Loading 9 Torsion 10 Bending stresses in beams 11 Shear stresses in beams 12 Combined loading 13 Transformation of stress (strain) components 14 Design of beams 15 Columns

Learning Outcome

Upon the completion of the course, the student should be able to

• use vectors to represent the force acting on a system and correctly plot free body diagram and check the equilibrium of a rigid body
• know the types of internal loadings, the relationships between stress and strain and the basic mechanical properties of materials
• compute the stress of a beam section due to tension, compression, torsion, bending, shear and combined loading
• transform stress (strain) components from one orientation to another
• learn the concepts for the design of beams
• correctly compute the critical buckling load of a column
