This video shows a workout on stress distribution due to the action of bending moment on sections made of two different materials through the application of transformed section. Very first, the video illustrates the given exemplary composite sections of two materials having steel at top and bottom & timber at the middle. Subsequently it explains the data given e.g., modulus of elasticity of steel & timber, value of positive bending moment subjected to the composite & the dimension details. Next, the video converts the composite to only steel material using the theory of transformed sections.

Moving on, the video works out on the new section and calculates the second moment of area under the given positive bending moment; successively does the calculation for stress distribution of steel material. Later, the video uses the transformed sections theory to find out the stress distribution of timber and finally plots all the obtained values over the schematic of composites sections to get the stresses distribution graphically.
