```Take the first derivative of the moment equation, set it equal to zero,
solve for "x", make sure "x" is indeed a global maximum (not just a local
maximum or minimum).

The inflection point would be determined from the second derivative of the
moment equation...not needed for this calc.

I think you should write another equation to determine the point of
inflection of the moment equation and then solve the moment equation at that
point.

Sorry this is a mathcad question,

I am trying to find the maximum moment on a beam with several loads.

I have writen a function to plot the moment diagram,

My question is, How do I extract the maximum moment out of my moment
function.

Thanks to all the mathcad masters
