Shigley's Example 3-3 Shear Force and Bending Moment Diagrams using MacCaulay/Singularity Functions

Shigley's Example 3-2 Shear Force and Bending Moment Diagrams using MacCaulay/Singularity Functions Step 1: Write the Load function, q(x), using MacCaulay (Singularity) functions Step 2: Integrate to find the Shear Force function, V(x) Step 3: Integrate again to find the Bending Moment function, M(x) Step 4: Plug in V=0 and M=0 at a location just to the right of the end of the beam to solve for the reaction forces on both sides Step 5: Draw the Shear Force diagram Step 6: Draw the Bending Moment diagram Important: 2 ways a MacCaulay term = 0: 1. x less than a (therefore the term is not turned "on" yet) 2. the exponent is less than 0 (technically it's undefined, but we replace it with 0) R.
