How long until a panel heats through?
Panels, projectiles and cooling, where the answer hides in a few uncertain constants.
The question
A panel is heated from one side. The far side warms up along a curve whose speed depends on one uncertain number. Shake that number and the time to reach your limit becomes a range.
What the model assumes
Lumped model, example numbers, one time constant as the unknown.
Results are hypotheses, not facts. Example models use round example numbers, not measured data. See honesty rules.
