The key objective of this video is to explain transformed sections and this is just going on from the previous theoretical video 5.12 of stress and strain in composite beam. At first, the video assumes a cross sectional (composite) made from materials having elastic modulus E1 and E2. Next, the video shows how material 1 can be converted to material 2 by multiplying the width by a factor of n. The factor ‘n’ represents the modular ratio of the composite element.
Moving next, the video converts the top material to bottom material using the conversion formula. Even though the conversion takes place, however, the neutral axis remains unchanged. To work out on stress distribution, the I-value for the transformed section must have to be calculated. To meet the necessity, the video introduces the formula of stress distribution for the materials that has been transformed. Later, the video shows the conversion of bottom material to top material and explains the transformation of the sections in greater details.

Course Description
This course builds on the concept of force and moment equilibrium learnt from first year engineering mechanic and physics courses and focuses on the internal actions and deformations experienced by simple structural members under loading. Concepts learnt in the course such as load transfer through axial, shear, bending and torsion as well as stress and strain relationships are the foundation for further study in any structural engineering related courses.
