I think that there is a lot of informations on this theme in Hebert & 
Ekelund's The secret origins of Microeconomics. 
There is also a French scholar, François Vatin, who is interested in the 
subject and had published a few book studies on French 19th century 
engineer economists (Cournot, Dupuit and lesser-known figures) and the way 
their 
economics has drawn upon the engineering knowledge of the time. I think 
that he deals quite specifiquely with the kind of topics you were asked 
upon. Alas for those who do not read French, there are not translated yet.
