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.
