The modular ratio of the materials used in the flitched beam is $10$ and the ratio of the allowable stresses is also $10$ . Four different sections of the beam are shown in Fig. 10.67. The material shown hatched has larger modulus of elasticity and allowable stress than the rest.

Which one of the following statements is true for the beam under consideration?

- 1
  
  All the given sections would support the same magnitude of load.
- 2
  
  Sections 2, 3 and 4 would support equal loads which is more than what section 1 would support
- 3
  
  Sections 1 and 2 would support equal loads which is more than what sections 3 and 4 would support
- 4
  
  Section 2 would support the greatest load
