Questions about example sentences with, and the definition and usage of "Avail"

A:
It means you tried something but it didn’t work out.

Example:
I studied hard for my test but it was to no avail. I still got a bad grade.

A: it means "I'm not helpful" or "I'm not beneficial"
the word "avail" is not commonly used

A: To "avail yourself of" basically means to take advantage of something that is available, like a resource. So this sentence is saying, "Make use of big men with guns to make money from scared girls." It seems that it might be talking about exploiting the fear people have to make money, aka "fear-mongering". I would have to know the context of what you're reading to know if that's a correct interpretation, though. To me, it sounds like a metaphor for the way that America perhaps uses fear-mongering (which is basically "selling fear") in their news channels and pretty much everything on tv to make the public afraid of certain things so that they will go out and buy things to protect themselves, or perhaps contribute more to the military. Here's an example of a made-up headline that would be considered fear-mongering:

"BREAKING NEWS! North Korea launches missiles at Japan. Is America prepared for a Third World War?"

See, so even if North Korea doesn't mean to start another war, they have people panicking because they're basically saying war is inevitable. Panicked people means irrational people who will spend money on whatever you tell them they need to prepare for war.

Hopefully that makes sense. Not trying to diss America. That's just the only place I've learned uses this tactic, but I'm sure it's not the only place it's done.

A: 'To be of no avail' is quite right. It means that something is futile. 'I ran as fast as I could to try and catch the bus, but it was all to no avail.'

A: The second one is correct and sounds natural. Also, you can change the working of 1 to make is correct as follows:

I tried to sleep, but it was all in vain.

Here, "in vain" has the nuance of "wasted effort."

"No avail" is similar but focuses more on the result being unsatisfactory.

Another way to say this would be "I tried to sleep but it was no use."
