A round bar ACB of length 2L (see figure) rotates about an axis through the midpoint C with constant angular speed v (radians per second). The material of the bar has weight density g.
(a) Derive a formula for the tensile stress σx in the bar as a function of the distance x from the midpoint C.
(b) What is the maximum tensile stress σmax?
