Course Objectives

Statics is a fundamental course in Mechanical Engineering. It purely emphasizes on bodies that are in Static Equilibrium (i.e. either they are at rest or moves with uniform velocity). The course of Statics is of particular significance because of the extensive use of its principle/techniques in the other core courses of mechanical engineering.

Course Learning Outcomes (CLO)

  1. CLO-1: Comprehend concepts of vectors and scalars, conditions of equilibrium for particles and rigid bodies in two and three dimensions. (C2)
  2. CLO-2: Analyze structures such as trusses, beams and frames for reaction forces. (C4)
  3. CLO-3: Explain the concepts of shear and bending moment of beams and the concepts of dry friction. (C2)
