Answer 1

Explanation:

Flitched beam

A beam made up of two or more different materials assumed to be rigidly connected together and behaving like a single piece is known as a composite beam or a wooden flitched beam.
The figure shows the wooden beam reinforced by steel plates.
This arrangement is known as a composite beam or a flitched beam.
The strain at the common surfaces will be the same for both materials.
Also, the total moment of resistance will be equal to the sum of the moments of individual sections.
When such a beam is subjected to bending, the bending stresses and hence strains due to bending stresses at a ppoint are proportional to the distance of the point from the common neutral axis.
