A disk of radius $\backslash ($ R $\backslash )$ and mass $\backslash ($ m $\backslash ),$ rotates about its axis at the constant rate $\backslash (\backslash$omega$\_\{2\}\backslash ),$ while the whole assembly precesses at a rate of $\backslash (\backslash$omega$\_\{1\}\backslash ),$ which is not constant. Compute the reaction forces and moments in bar B at point O $,$ the point about which it is rotating. Draw a sketch showing the stresses that each of those cause in the beam in the $\backslash ($ x$\_\{1\}$ y$\_\{1\}\backslash )$ plane. What equations would you use to find each of the stresses in your sketch? What about the moment about the $\backslash (\backslash$mathrm$\{$x$\}\_\{1\}\backslash )$ axis? If needed, you may assume that the bar is a solid circular shaft with radius $\backslash ($ r $\backslash )$ in your analysis. Neglect the mass of the bent arm OC that supports the disk. Both of the bends in bar OC are at $90$ degree angles.
