Question : 160 of 200

Marks: +1, -0

Two identical simply supported beams of span ‘l’ are subjected to equal load ‘W’. One beam is carrying the load ‘W’ at its centre (as concentrated load) and the other one is carrying it in the form of u.d.l over the entire span. The ratio of their mid-span bending moment will be

$1/2$
2
4
8

Validate

Solution:

According to question

The ratio of their mid span bending moment

={{WL}/4}/{{ωL^2}/8}

(∵ωL=W)

∴{WL}/4×8/{WL}=2
