CAB $[26$ pts$]$ Massless arm CAB is in equilibrium and subject to a uniform distributed $800l\frac{b}{f}t$ force from $C$ to $A,$ which tapers down to $0l\frac{b}{f}t$ at $B.$ Also, concentrated couple moment $C_A$ is applied at A $.$ The beam is supported by a pin at C and a cable running over a frictionless, massless pulley that is attached at both A and $B.$

Find the magnitudes of the force and$/$or moment components at $C$ and the tension in the cable.
