Shear & Moment Diagrams, step by step

Works for simply supported spans, cantilevers and overhangs.

  1. Find the reactionsSum vertical forces and take moments about one support.
  2. Cut from the leftShear at a section is the sum of all forces to its left.
  3. Draw the shear diagramA point load steps it, a UDL slopes it, and it must close at zero.
  4. Integrate for momentArea under the shear diagram is the change in bending moment.
  5. Locate the peakMaximum moment sits where the shear crosses zero.
  6. Check the endsMoment is zero at a simple support and at a free cantilever tip.

UDL w on a simple span L

  • Reactions wL/2 at each end
  • Shear falls linearly from +wL/2 to −wL/2
  • Shear is zero at mid-span
  • Maximum moment = wL²/8

Questions about the Shear & Moment Diagrams poster

What’s on the Shear & Moment Diagrams poster?
6 numbered steps, with a full worked run-through. Works for simply supported spans, cantilevers and overhangs. Find the reactions — Sum vertical forces and take moments about one support.; Cut from the left — Shear at a section is the sum of all forces to its left.; Draw the shear diagram — A point load steps it, a UDL slopes it, and it must close at…; Integrate for moment — Area under the shear diagram is the change in bending moment.; Locate the peak — Maximum moment sits where the shear crosses zero.; Check the ends — Moment is zero at a simple support and at a free cantilever tip.. Educational reference. Diagram shapes are analysis; sizing the member needs a code and a qualified engineer.
Who is the Shear & Moment Diagrams poster for?
Shear & Moment Diagrams belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning structural analysis can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Shear & Moment Diagrams poster?
Use it whenever you need where the beam is worst, not just how bad. A wall chart earns its place by being glanceable from where the work is happening, so Shear & Moment Diagrams belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Shear & Moment Diagrams?
Braced vs Moment Frame, Beam Reactions and Bending Stress sit alongside Shear & Moment Diagrams in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Braced vs Moment FrameBeam ReactionsBending Stress
Is the Shear & Moment Diagrams poster free to download and print?
Yes. Shear & Moment Diagrams downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Shear & Moment Diagrams poster print at?
Shear & Moment Diagrams is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Shear & Moment Diagrams loses nothing.Printing guide
