HW$17\_$#$1-$ DISTRIBUTED

The beam is subjected to the distributed loads shown and supported by a rocker at C and a pin at A$.$ Assume the rocker can support vertical forces either up or down. Point D is located halfway between A and B$.$ Point E is located halfway between B and C $.$

A$.$ Find the support forces at A and C$.$

B$.$ Draw both FBDs $($above and below cut$)$ you could use to solve for the internal axial force $(A{D}_D),$ shear force $(V_D),$ and bending moment $(M_D)$ at point D $.$

C$.$ Draw both FBDs $($left and right of cut$)$ you could use to solve for the internal axial force $(A_E),$ shear force $(V_E),$ and bending moment $($ ME $)$ at point E$.$

For $B$ and C: Make sure all internal loads $($A$,$V$,$& M$)$ on FBDs are drawn in the assumed positive direction. Represent distributed loads as equivalent point loads; do not solve for $A,V,$ or $M$ values.
