What’s on the Bending Stress poster
The rule, 3 worked examples, and the mistake everyone makes.
- Bending stress varies linearly through the depth: zero at the neutral axis, greatest…
- σ = My/I · σmax = M/Z · Z = I/c
- M 40 kNm, Z 5×10⁵ mm³ = σ = 80 N/mm²
- Double the depth = Z rises about 4 times
- Where is stress zero? = At the neutral axis
- Common mistake: Measuring y over the full depth → Measure from the neutral axis
Educational reference. Elastic theory, symmetric section, bending about a principal axis. Design follows the code.

- Who is the Bending Stress poster for?
- Bending Stress 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 Bending Stress poster?
- Reach for it when checking whether a section is deep enough. A wall chart earns its place by being glanceable from where the work is happening, so Bending Stress belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Bending Stress?
- Braced vs Moment Frame, Beam Reactions and Column Buckling sit alongside Bending Stress 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 ReactionsColumn Buckling
- Is the Bending Stress poster free to download and print?
- Yes. Bending Stress 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 Bending Stress poster print at?
- Bending Stress 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 Bending Stress loses nothing.Printing guide
