F7 11 Determine The Shear And Moment As A Function Of X Where 0 X 3 M And 3 M X 6 M And Then Draw The Shear And 1 (91.1 KiB) Viewed 43 times

can you please explain these two exercises to me?
my mayor doubts are:
-F7.11: when we make the cut at C, why we don't take into consideration the 30 kNm moment that is applied at that point?
the answer for 7.11 should for the region 0<x<=6 M=5(6-x) kNm
-F7-12: basically the same thing.. when we cut at C then we don't take into consideration the 4kN force??
