Twо bаrs hаve the sаme mоment оf inertia around their horizontal centroidal axes. The hollow bar has an outside diameter of 1.900 in. and a wall thickness of 0.380 in. Determine the diameter of the solid bar. Explain the relationship between the preceding problem and Enlightenment movement but leave the problem unsolved.
