A crank-rocker mechanism is given with the following dimensions as shown below. $?2=120^{?}$ and it moves with a constant angular velocity $?2=18\mathrm{rad}/\mathrm{s}$. The external forces acting on points $\mathrm{B}$ and $\mathrm{C}$ are $\mathrm{F}=2000\mathrm{N}$ and $\mathrm{F}=$ $1000\mathrm{N}$, respectively. Perform a dynamic force analysis of the system. (PÇ-1, PÇ-2) a) Find the inertia forces and moments acting on the link ABC. (10P) b) Draw the free body diagrams of the mechanism's links. (10P) c) Determine the position of the equivalent inertia force and indicate it on the diagram.
