Understanding Bending Moments and Moment Equilibrium in Structural Analysis

[QUOTE="PhanthomJay, post: 6306582, member: 58874"] you can take the sum of moments about [I]any[/I] point equals 0 for equilibrium problems. You will note that you correctly identified V=A, so your equations 1 and 2 are exactly the same. It is often best to sum moments about a point where there are loads given or unknown, to make the solution easier. it would be good to see a sketch of this problem. If there is no vertical load it is not a buckling case. But still you can take moments about any point...your equation is better written as P*v(x) - M(x) - Q = 0. Taken about the other end, it’s +P*v(x) - Q - M(x) = 0, which is the exact same result. Show a sketch to check out your plus and minus signs. [/QUOTE]
