  Lecturer : SHEK POI NGIAN Semester  :  Semester 2 2014/2015
  Synopsis : This is a subject of the basic theory of the fundamental principles of mechanics of materials. Students will be able to incorporate these basic fundamentals into application of the basic design of simple structures . It will assure them of the concepts of stress and strain, plane-stress transformation, shear force and bending moment, stresses in beams, analysis of statically determinate plane and space trusses, deflections of beams, columns, and torsion. At the end of the course, the students should be able to solve numerous problems that depict realistic situations encountered in engineering practice. The students will also be able to develop and master the skills of reducing any such problem from its physical description to a model or symbolic representation to which the principles may be applied.
