#$2(8$ pts$)$: Calculate the necessary force F so that there is no rotational tendency in the body.

#$3(7$ pts$)$: Calculate the magnitude of the couple moment acting on the system if d$=370$mm and

F$=450$N$.$ #$4(8$ pts$)$: Replace the distributed loading by an equivalent system with one force and specify its line

of action $($how far from point C$).($Ignore the supporting reactions from the pin and rope.$)$
