A) True 

B) False 

10. A simply supported beam 'A' of length l, breadth b and depth d carries a central point load W. Another bream 'B' has the same length and breadth but its depth is doubled. The deflection of beam 'B' will be double as compared to beam 'A'.

A) Agree 

B) Disagree

A) Yes 

B) No
