It has a subjective component, no doubt, but a technician must design with objective values that prevent excessive deflection, which...

TANSL attached a file to the thread Dimensioning of plywood cockpit floor.
I have attached a document in which I explain how I calculate the deflection of the stiffeners.

TANSL replied to the thread Dimensioning of plywood cockpit floor.
The ISO standard considers that the panels have all four edges fixed, not supported. Based on this assumption, I use the formulas from...

TANSL replied to the thread Floodable Length and Compartment Standard.
Welcome to the forum. I assume you're referring to the study of stability after damage (not the calculation of floodable lengths). Each...

TANSL replied to the thread Sponson Math - Stability Deltas.
It would be helpful to specify the parameter you are using to define stability. If you are referring to initial stability, or...

TANSL replied to the thread Dimensioning of plywood cockpit floor.
It's a bit late to review your calculations, so I won't do it until tomorrow. Regarding deflection, I don't think I explained myself...

TANSL liked TopliCar's post in the thread Jet drive, up to 21 ft, deep V, aluminium- plans needed.
Barry, to be completely honest, you are wasting both yours and mine time and energy. If i asked for those specifications there must be a...

TANSL replied to the thread Dimensioning of plywood cockpit floor.
I calculate the panels, in general, so that their maximum deflection is less than half their thickness. Consider a load of 4 people per...
