Concepts¶
Short primers on the ideas that run through every BriskFyr model. Each is half a screen, not a textbook chapter — and links to the tutorial where the idea shows up live. Read them in any order, or only the one you need.
-
Why a free body has 6 DOF, and why counting them is how you check a mechanism can move before you ever run it.
-
A joint doesn't add motion — it takes freedom away. What's left over is what moves.
-
A push or a twist, shaped over time:
load(t) = magnitude × drive(t). -
Restoring force vs. velocity resistance — and the damping ratio that decides whether a system oscillates, settles fast, or crawls.
-
How to name a point that isn't a body, and read an exact number instead of judging motion by eye.
-
Why every field is SI, and what that means for you day to day.
-
Why every tutorial ends with a hand-calculated number — and how to hold your own models to the same standard.
