Question $1$: Replace the three forces applied to the beam by an equivalent force$-$couple system with the force acting at point A

Part $3$: Using the components calculated in part $1,$ and Moments in Part $2,$ select the right answer for the equivalent Force$-$Moment System at point A$.$ Angle $$ is the

angle with $x-$axis.

a$.FR=1010lb,=83\mathrm{.}9,$ Total Moment $=-11,190lb.ft$

b$.FR=590lb,=46\mathrm{.}5,$ Total Moment $=-11,190lb.ft$

c$.FR=940lb,=76\mathrm{.}5,$ Total Moment $=-11,190lb.ft$

d$.FR=640lb,=83\mathrm{.}9,$ Total Moment $=-8,190lb.ft$

e$.FR=1010lb,=83\mathrm{.}9,$ Total Moment $=+11,190lb.ft$
