about Roads, Bridges and Dams; 2. Comprehend the action of Forces, Moments and
other loads on systems of rigid bodies; 3. Compute the reactive forces and the
effects that develop as a result of the external loads; 4. Locate the Centroid
and compute the Moment of Inertia of regular crosssections. 5. Express the
relationship between the motion of bodies and 6. Equipped to pursue studies in
allied courses in Mechanics.

**Question Paper Pattern:**

• 10 Questions are to be set such that 2 questions are selected from
each module. • 2 Questions are to be set under respective modules. • Intra
module questions are to be set such that the questions should cover the entire
module and further, should be answerable for the set marks. • Each question
should be set for 16 marks (Preferably 8 marks each) • Not more than 3 sub
questions are to be set under any main question • Students should answer 5 full
questions selecting at least 1 from each module.
