How exactly does a Voussoir function as an active component within a true arch????
How does a true arch function as opposed to a gabled arch???
Are they the same?
Are they different??
What is the difference between a True Arch and a False Arch??
What would happen if we were to remove the lower cross member from a triangulated truss??
If the lower cross member of a truss were removed could it be compensated for in any other way therefore mathematically maintaining the structural integrity of the truss??
I look forward to your answers.
I have corrected and completed your drawing.
