I don't know what jmcnamara meant when he offered up his example - I'll assume that he knew what stress and strain are.
Indeed I do. I have a masters degree in Mechanical Engineer. :-)
That was a very clear explanation of the mechanical concepts. I was referring instead to the vernacular use: "He is under a lot of stress at work, I hope he can take the strain".
And just to out nit-pick you. Hook's law only applies for elastic materials in their elastic range. And even for elastic materials you can have stress without strain and strain without stress. But let's not get into all of that. ;-)
