Drawing Shear & Moment, step by step
Work left to right, and let the calculus check your sketch.
- Find the reactionsWhole-beam equilibrium first, before you take any cut.
- Mark every discontinuitySupports, point loads, and where distributed loads start and stop.
- Build the shear diagramShear jumps at a point load and slopes under a distributed load.
- Integrate shear into momentMoment at a section is the shear area to the left of it.
- Locate the maximum momentWhere shear crosses zero, or at a built-in end.
- Check both endsShear and moment must both return to zero at a free end.
dV/dx = −w and dM/dx = V. If your slopes disobey those two, the diagram is wrong.

- Who is the Drawing Shear & Moment poster for?
- Drawing Shear & Moment belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning mechanics of materials can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Drawing Shear & Moment poster?
- Before sizing any beam: the maximum moment is what sets the section. A wall chart earns its place by being glanceable from where the work is happening, so Drawing Shear & Moment belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Drawing Shear & Moment?
- Axial Stress & Strain, Beam Bending Stress and Beam Deflection Cases sit alongside Drawing Shear & Moment in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Axial Stress & StrainBeam Bending StressBeam Deflection Cases
- Is the Drawing Shear & Moment poster free to download and print?
- Yes. Drawing Shear & Moment downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical 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 Drawing Shear & Moment poster print at?
- Drawing Shear & Moment 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 Drawing Shear & Moment loses nothing.Printing guide
