why I-sections are considered to be stronger one than any
other ?
how does a ship floats?

Answer Posted / mr. sachin lotan borse

1)Moment of Inertia of 'I' cross section is geater than that
of same cross sectional area rectangular area. Hence it will
not bend for load it bends with rectangular section
2)Ship floats because of Buoyancy force. When body is placed
in liquid force acts on it in upward direction called as
Buoyancy force. Value of this force is equal to weight of
liquid displaced by body submerged in fluid. Any body will
able to float in fluid if mass of body is less than mass of
fluid displaced by body if totally immersed in fluid.
