Few clarification :
.for material resistance, stress analysis, the term "girder" or "beam" designates a long part whose dimensions of its section are smaller.
A gider can have sections like L, T, H, I, square, rectangle, round etc. .. or Z like on the Morgan.
"In the case you describe, they will bend and stay that way. But they will still remain flexible "
. In term of resistance a steel is characterized by :
Re : Elastic limit
Rr : Rupture limit
Below the Elastic limit, the material can bend under a force and return to its initial position when the force is released. It is in the elastic domain. Applying a force ahead you distort the material, by instance to transform a plate to a Z girder. If you continue to apply the force and you reach the rupture limit, you break the material.
Calculation of structure take into account the Elastic limit with a security coefficient in order to don't exceed the Elastic limit in order to remain in the elastic domain.
I don't know the steel used by MORGAN, but generaly steel with a Re above 30 daN/mm² is used… I hope.
"I don't think Morgans are susceptible to formulas"… Why not ? I hope Newton, Young and others are deaf and are not rolling in their grave!
