Shear and Bending Moment Diagrams!! 1. The problem statement, all variables and given/known data 2. Relevant equations Newton's 2nd and 3rd 3. The attempt at a solution So my main confusion is this: I found the reaction at A to be 19 kN If I make a vertical cut through some arbitrary point along the beam and and do some analysis I get: From the left portion: [tex]\downarrow +\sum F_y=0\Rightarrow V-19+3x=0\Rightarrow V=19-3x[/tex] Now if I take the right portion I get: [tex]\uparrow +\sumFy=0\Rightarrow V-10-[3(6-x)]=0\Rightarrow V=28-3x[/tex] Now which do I use? Or How do I go from what I have to a shear diagram?
