What is observed.
What is still unknown.

These are fictional teaching records. No real measurements, tests or performance findings are claimed. The distinction between a visible condition and a conclusion is the point.

G-APivot clearance

Is the apparent side movement caused by clearance at the pivot or by another joint?

Authored observation

In the fictional no-load hand check, the board shifts slightly sideways before rotating. The section sketch shows a visible gap either side of the moving lug.

Evidence limit

The sketch and observation do not measure the gap, locate all play, establish tolerance or predict wear.

Unmeasured / unverified: Actual pin diameter, hole sizes, axial stack and where movement originates remain unmeasured.

G-BClamping contact

Does the washer meet the cheek evenly before the knob begins to resist rotation?

Authored observation

In the fictional contact-mark check, the transfer mark is stronger along one washer edge. A heavier mark suggests uneven contact but does not measure pressure.

Evidence limit

One mark cannot establish clamp force, safe tightening torque, friction capacity or reliable holding performance.

Unmeasured / unverified: Face alignment, washer flatness, thread condition and the relationship between knob effort and contact force remain unknown.

G-CAngular support

Does the prop seat fully in the selected notch through the intended no-load adjustment sequence?

Authored observation

In the fictional side-view check, the prop appears to touch one edge of the selected notch before its foot settles. The view identifies an engagement question, not a failure.

Evidence limit

A side view does not prove engagement depth, resistance to release or load capacity. No loaded use has been assessed.

Unmeasured / unverified: Actual notch shape, prop-foot contact, lateral retention and behavior under disturbance remain unverified.

Inspect relationship and select next evidence

A useful record keeps
its conditions attached.

  1. Identify the object and setup. State which parts, position and condition were observed.
  2. Record the method. Explain how the observation or measurement was made.
  3. Separate observation from inference. A contact mark is not a force measurement.
  4. Carry the unknown forward. Name what a later investigation would need to establish.
