why I-sections are considered to be stronger one than any
other ?
how does a ship floats?
Answer Posted / aravindan.s
I-sections are having high section modulus value.
section modulus=(moment of inertia about the neutral
axis)/(distance between neutral axis and topmost layer of
the beam)
This section modulus value is greater for I-section beam.
according to nature of bending stress, inensity of stress is
maximum at top and bottom layer of beam. the stress is zero
at neutral axis.Due to this nature of bending stress, at top
and bottom part of I-beams are provided with wider flange
and a thin web at centre part.so less amount of material is
enough to made i_beams to withstand more bending and shear
stress than any other beams.
