Note * : R_{1} and R_{2} are vertical end reactions at the left
and right, respectively, and are positive upward. Shear forces and deflections
are positive in upward direction and negative in downward direction. M_{1} and M_{2} are the reaction end moments at the left and right, respectively. All
moments are positive when producing compression on the upper portion of the beam
cross section. All slopes are positive when up and to the right.
Note: Stresses are positive numbers, and these are stress magnitudes in the
beam. It does not distinguish between tension or compression of the structural
beam. This distinction depends on which side of the beam's neutral plane c input
corresponds.
