Can some one explain the difference between those two? examples?
confused...Thanks

 

[wingman]

in what context?

E.g. "Suggest a service property and an engineering property of wood as a roof beam"

Engineering properties: Flexibility, bending moment, density, hardness, degree of degradation, workability, reliability etc.

Never heard of service property, sorry! Where are you quoting from?
