It's no use trying to lift the safe on your own. You need somebody to help you.

It's no use trying to lift the safe on your own. You need somebody to help you.

Is the sentence OK? Thanks.

 

[5jj]

Fine.

 

[BobK]

:up: - so long as it means 'Don't bother trying. You just won't be able to do it' - which is what no use means here.

How about the following sentence? Is it also correct?
It's no use in trying to lift the safe on your own. You need somebody to help you.

 

[Rover_KE]

No. Adding 'in' makes the sentence incorrect.

As an NES but not a teacher, I believe "in" would work in the context of "There's no harm in trying to ..........", although not in the current context.

Or There's no point in trying...

 

[anhnha]

Thanks, actually I have consulted "no use" in my dictionary and seen the sentence:
There is no use in crying about your broken bike．

 

[Rover_KE]

That's not the same as 'It's no use in trying...'
