|"She has got over the most trying age."|
This can be in the sense of seeing if something works, or of making something difficult. Think of Lizzie saying to Wickham that Georgiana "has got over the most trying age." Or Mrs. Bennet saying that something tries her nerves, or tries her patience.
You might say "try the door," which would mean, test the door, or see if the door will open. Saying, "I have tried to open the door," is not as elegant, in my opinion, and not as common a historical usage.
|"It ought not to be attempted."|
My feeling is that it will make your writing more authentic if you are aware of these different meanings of "to try" and if you mostly use it in the sense of testing the capacity of something, or being difficult, and if you mostly use other words when referring to one's exertion.
