AR6201 Mechanics of Structures - 1

OBJECTIVES:
 To enable a student to understand the effect of action of forces on a body and the
concept of equilibrium of the body through exercises.
 To determine the internal forces induced in truss members due to external loads by
working out problems.
 To calculate the sectional properties (centroid, moment of inertia, section modulus and
radius of gyration) for various sections by working out problems.
 To study the stress – strain behaviors of steel and concrete due to axial loads and to
determine the stresses and strains developed in solids due to external action through
select problems.
 To derive the relationship between elastic constants and solving problems.
