Question $5.$ The shaft with two levers shown here is used to change the direction of a force. Determine the force $\backslash (\backslash$mathbf$\{$P$\}\backslash )$ required for equilibrium and the reactions at supports A and B $.$ The support at A is a ball bearing $($no reaction force along the line AB $)$ and the support at B is a thrust bearing $($a reaction force along the line AB $),$ both bearings exert no moment forces on the shaft.
