1. The problem statement, all variables and given/known data
Note the attachment. I scanned it out of my book and I drew a FBD on it.

2. Relevant equations

3. The attempt at a solution

Ok so i havent gotten very far at all with this one because it just doesnt seem to have enough information.

So first I summed the forces in the y direction.

Fy = 0 = 9k - RB.... RB = 9k

Then I found the Moment @ B

MB = 9k(192) = 1728k

and thats about as far as I got. It seemed odd that there was no information given about the forces or distances at point A.

so I know that the Bending stress = -My/I

but how do I find the y. Im assuming it would come from k = 1/p but I do not know any of those quantities. Same with I = integral y2dA. Can I get a hint as to my next step
