Expert Answer

Step 1

Deflection of beam is in inversely related to the modulus of elasticity. The material having the maximum value of modulus of elasticity will be selected in order to get minimum deflection.

Step 2

From the given table in question,

The value of young’s modulus of elasticity of different material.
