ME2151 ENGINEERING MECHANICS  SYLLABUS 3 1 0 4
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.
