What’s on the Beam Deflection Cases poster
A 5-row table: Beam and load · Maximum deflection.
Small deflection, linear-elastic material, constant EI along the span.
- Cantilever, end load P — PL³ ÷ 3EI
- Cantilever, uniform load w — wL⁴ ÷ 8EI
- Simple span, centre load P — PL³ ÷ 48EI
- Simple span, uniform load w — 5wL⁴ ÷ 384EI
- Both ends fixed, uniform w — wL⁴ ÷ 384EI
Deflection goes as the cube or fourth power of span. Halving the span cuts it by 8 or 16 times.

- A 5-row table: Beam and load · Maximum deflection. Small deflection, linear-elastic material, constant EI along the span.

- Who is the Beam Deflection Cases poster for?
- Beam Deflection Cases 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 Beam Deflection Cases poster?
- Serviceability checks, where stiffness rather than strength sets the size. A wall chart earns its place by being glanceable from where the work is happening, so Beam Deflection Cases belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Beam Deflection Cases?
- Axial Stress & Strain, Beam Bending Stress and Transverse Shear Stress sit alongside Beam Deflection Cases 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 StressTransverse Shear Stress
- Is the Beam Deflection Cases poster free to download and print?
- Yes. Beam Deflection Cases 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 Beam Deflection Cases poster print at?
- Beam Deflection Cases 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 Beam Deflection Cases loses nothing.Printing guide
