Question: In Figure, the bar of mass 2m and length 2l is supported by two massless cords and is acted on by a known horizontal force f(t). The cords on the left and right have lengths l and 2l, respectively
Tasks: (a) Draw the system in a general position, select coordinates, and state the required kinematicconstraint relationships.
(b) Draw a free-body diagram for the bar in a general position and develop governing equations of motion.
(c) State the equations for your unknowns in matrix format.
