b0 ? 1 for b 0 (9) b0 ? 0 for b>0 (10)Referring to the beam ab in Fig. 1, we may, for illustrative purposes, employ the rudiments ofsingularity functions and observe the defined sign conventions for beams to write the loadingfunction q, the shear force V, and the bending moment M for of this beam as follows:6-8 q ? Va > x @ /1 - M a > x @ /2 / P > x / xP @ /1 - K > x / xK @ /2 w1 / w0 > x / xw @ 0 / > x / xw @1 (11) L / xw

upward displacement. Page 12.240.3 A positive slope is a counterclockwise angular displacement.III. Derivation of Model FormulasAny beam element of differential width dx at any position x may be perceived to have a left faceand a right face. Using singularity functions,8-10 we may write, for the beam ab in Fig. 1, theloading function q, shear force V, and bending moment M acting on the left face of the beamelement at any position x for this beam as follows: q ?
