Shear and bending moment diagram problem

Homework Statement


I have attached a diagram


Homework Equations


14 + Va -32 + Vb -15=0??
or Vb=-15?

The Attempt at a Solution


The reason why I cannot attempt this problem is that I'm not sure whether it is valid that there can be a point load at Support B or whether they are implying that Vb=-15kN.

After I get Va and Vb I know what to do :)

This is the only issue I need to clarify.

Cheers

Yes you can have a point load over the reaction point. It just adds its value to that obtained from the other loads. In every case of calculating reactions, you should check it, for example by taking moments about a point not used in the original analysis. In that case you do not need help in answering the question.
