how could water carve the grand canyon if water is softer than rocks?
Well, sort of. But not by water alone. The sediments, sand, pebbles, stones and boulders carried by water over time did most of the work. Later on, the exposed, sculptured elements were further eroded by wind and rain and the sand, dust, etc. carried by them.Quote:
Exactly. Any matter can erode a harder substance with enough frictional interaction.how could water carve the grand canyon if water is softer than rocks?
Yup. Some of the best wet/dry sandpaper you can buy is aluminum oxide sandpaper.Aluminum oxide is an extremely hard material, it makes a fantastic abrasive.
The modulus of elasticity of steel is the same between grades no matter what has happened to them. The term that you are referring to is the yield point, and then it would be the stress in the steel imparted by the internal pressure of the barrel, and those two things are not the same.If they were, then they would bell and deform the first time you shot a round through it unless you kept the pressure under the modulus of elasticity of the material. In which the round velocity means you may as may as well use a slingshot.
After you've seen a zillion M1's with egg shaped muzzles, devoid of rifling, you start to believe that careless and overly aggressive cleaning really is bad.
And not only M1s, many, many milsurps show the evidence of muzzle wear from cleaning rods. Yet some people refuse to believe that cleaning rods cause wear.Quote:

+1
Maybe the problem is not the cleaning but milsurps that have tens of thousands of rounds through them, under bad circumstances, and been cleaned with whatever horrible cleaning kit they came with.
All aluminum... the can of soda, the engine block, or the cleaning rod, has an extremely thin layer of aluminum oxide. Scrape it off and a new layer forms in seconds.

Well, not shooting it just kinda takes all the fun out of it.Don't hit your equipment with a mallet or shoot it
