The simply$-$supported beam is loaded as shown.

a$)$ Determine the location of the resultant of the given distributed load acting on the beam from the roller support. $($Ib$)$

b$)$ Is there any couple effect produced at point C$?$ If so$,$ what will be the magnitude and direction of the resulting couple moment? Use CCW for counterclockwise and CW for clockwise. If not, please write $\text{'}0$ lb$-$ft$\text{'}$ in the given box. $($lb$-$ff$)$

a$)$ Replace the loading system by an equivalent resultant couple moment acting at the hinge support. $($lb$-$ft$)$
