A narrow uniform bar of density
ρ
and length 2b
is rotating with an angular velocity
ω

about an axis perpendicular to the bar through its center. Neglecting gravity effects and

assuming linear elastic behavior, determine the increase in length of the bar resulting

from the rotation.

.
Assume the plate o is linearly elastic. Determine the stress components

σx, σy
and the displacement component
v
as functions of
y.
