Of just mechanical engineering, but not just applied mechanics which can cover things other than machines.

@Phil In practice I tend to make these decisions on a final (third) read through of the document so it fits with the style and purpose. Here I just tend to give posters all options, just as I do for myself on a first draft.
I tend to use literal translations when I feel people might want to trace it back, which is the case here. A native English prof on the telephone to an Italian secretary (or lecturer for that matter) with a little English asking "Do you have a course called 'Mechanics applied to machines'?" would probably get further than one asking about a course in "Mechanical Engineering". Said that, IMHO the literal translation would hardly impress a prospective native English employer. On a final read, I'd probably strip it right down to mechanical engineering, that way he might actually get to the stage where they check his references.
