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

Should I use the sum of moments or?

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.

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 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
