When a rectangular beam is loaded transversely, the maximum tensile stress is developed on the

If it is Simply Supported, Wrong Answer. If it is Cantilever, answer is okay. But you have to specify it. Generally without a beam mention it is taken as Simply supported. So the answer is wrong...

*CANTILEVER BEAM* ---- Answer is A
Beam is hogging if it is cantilever beam. In case of hogging, the top surface is in tension and the bottom surface is in compression. And the neutral axis experience no stresses at all.
The top fibre of the beam undergoes maximun tensile stress and the bottom fibre of the beam undergoes maximum compression .

SIMPLE
WHEN LOAD IS APPLIED ON A BEAM
UPPER ZONE = COMPRESSIVE ZONE
LOWER ZONE = TENSILE ZONE
NOW
STRESS = RESISTING FORCE PER UNIT AREA
SO REVERSE THE ABOVE PHENOMENA
UPPER ZONE = TENSILE STRESSES
LOWER ZONE = COMPRESSIVE STRESSES
SO GIVEN ANS IS CORRECT

Answer must be B if its simply supported beam. Otherwise A (cantilever)

If beam is cantilever, then answer is correct

B

I think it should be B
