(adsbygoogle = window.adsbygoogle || []).push({}); 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?
