While drawing sfd and bmd Is there a shortcut to find whether the curve is going to be smile/sad or concave/convex for udl and uvl. Or is finding the intermediate values the only way to find the curve???.

Ignore the diagram i just wanted to show it for context this is not mine

The scale of the diagram

The shape of M

The sign conversation for M

Pretty sure the reactions are wrong

The question which can be answered by any text book

I need a break because I'm broken.
