What’s on the Moments poster
The rule, 3 worked examples, and the mistake everyone makes.
- A body is in equilibrium when the resultant force and the resultant moment are both z…
- moment = F × perpendicular distance
- Principle of moments = Sum clockwise = sum anticlockwise
- Choosing a pivot = Pick one that eliminates an unknown
- Couple = Two equal opposite forces; moment = Fd
- Common mistake: Using the distance along the force's line → Using the perpendicular d…
Take moments about the point where the most unknowns act. Their moments vanish and the algebra collapses.

- Who is the Moments poster for?
- Moments belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning mechanics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Moments poster?
- Forces balance AND moments balance. Both are required. A wall chart earns its place by being glanceable from where the work is happening, so Moments belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Moments?
- Circular Motion, Free Body Diagrams and Friction & Drag sit alongside Moments in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Circular MotionFree Body DiagramsFriction & Drag
- Is the Moments poster free to download and print?
- Yes. Moments downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics 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 Moments poster print at?
- Moments 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 Moments loses nothing.Printing guide
