Direction: A steel beam of breadth 120 mm and height 750 mm is loaded as shown in the figure. Assume Esteel = 200 GPa.

  1. The beam is subjected to a maximum bending moment of
    1. 3375 kNm
    2. 4750 kNm
    3. 6750 kNm
    4. 8750 kNm
Correct Option: A

Maximum bending moment occurs at the centre

=
wL2
=
20 × (15)2
= 3375 kNm
