First if you mean strength you must beat the gym leader in pastoria city and she will give the HM strength. Then you teach to a Pokemon and you can use it.
If you mean stealth rock you can teach it to a Pokemon if you have the TM for it or sometimes your Pokemon will learn it.
I hope this is helpful
First you find the HM in the lost tower next to the hollow tower. then you get the badge from canlave city and your Pokemon can use strength
Find a Pokemon that can learn Rock Smash. Like Geodude.
There is no way to break the boulders that don't have cracks. I've played through the game a few times and I don't recall coming to any place where you need to break one to get to an item or anything.
It doesnt really matter. I used my starter Pokemon. But if that doesnt work use a Pokemon that does a lot of damage to it. ex: Rock Pokemon= using a water Pokemon!
In the oreburgh mine this goes for pokemon diamond pearl and platinum
Teach the HM Rock Smash to a Pokemon and interact with the rock. Round rocks need the move strength and not all Pokemon can use these moves.

You need to teach strangth to at least one of your pokemon. The pokemon that knows strength must be in your party if you need to use strength. Click on the rock and answer yes when it asks if you would like to move the rock. Then just walk into the rock and it will move
