OBJECTIVE
At the end of this course the student should be able to understand the vectorial and scalar
representation of forces and moments, static equilibrium of particles and rigid bodies both in two
dimensions and also in three dimensions. Further, he should understand the principle of work and
energy. He should be able to comprehend the effect of friction on equilibrium. He should be able to
understand the laws of motion, the kinematics of motion and the interrelationship. He should also be
able to write the dynamic equilibrium equation. All these should be achieved both conceptually and
through solved examples.
