How do I find the supporting force $R_A$ and the moment $M_A$?

Should I use the sum of moments or?

Hello Rails, Welcome to Physics.SE. This is a site which supports conceptual Q&A posts and discussions relating such (as defined in our FAQ). On the darker side, it also discourages posts which specifically ask other users to solve a set of home-made problems. Please have in mind to read our homework policy before asking such questions :-) –  Waffle's Crazy Peanut Nov 28 '12 at 16:20

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

This is a statics problem, so yes, you should enforce that the sum of the forces equals zero, and the sum of the moments equals zero. For a uniformly distributed load, you can treat is as a point load applied at the midpoint of the distribution when calculating the moment at point A.

Where can i find moments from point A? –  Rails beginner Nov 28 '12 at 16:30
