Given: Particles A and B $($having masses of $m$ and $2m,$ respectively$)$ are attached to a lightweight

rigid bar as shown in the figure. A constant horizontal force $F$ acts on particle A$.$ At the initial

state of $=0,$ the system is at rest.

Find: Determine the angular speed of the bar as a function of $$ and in terms of the parameters of

the problem.
