Question
Note: the moment of inertia plays an important part in the theory of
deflection of beam under transverse loading where the flexural
stiffness is given by El where E is Young Modulus of Elasticity and I is
the moment of inertia of the beam cross section with respect to the
horizontal axis through the center of gravity. The greater the value of I,
the stiffer the beam and the less it will deflect.
For a uniformly loaded simply supported beam, the max deflection at
5 wl4
midspan is:
384 EI
