Aim of Subject: To introduce the students to the field of statics in applied mechanics.
Learning Outcome of Subject: At the completion of the subject, students should be able to :
  • Understand the fundamental concepts and principles in Newtonian mechanics.
  • Apply vector methods to define the moment of a force about a point and about an axis.
  • Solve equilibrium problems involving coplanar and three-dimensional forces.
  • Identify free-body diagrams that are used to solve equilibrium problems and to express the equivalence of two systems of forces.
  • Determine the internal forces which hold together the various parts of the structures such as trusses, frames and machines.
  • Determine the shearing force and bending moment at any point of the beam.
  • Compute the moments of inertia of various areas with respect to specified axes.
