why can the metal dent easily?

Car metal dents easily because it is designed to absorb collision energy.  The more it deforms, the more the impact is disappated- protecting the occupants inside.

scratches from the wrong untensils (never use metal on teflon coating) scrubbing them with brillo pads is also a big no no and even the smallest dent from ther pots and pans in yur cupboard will cause the coating to some loose. just like a cars paint one little scratch or ding or dent and it is all over.

Possibly the material underneath the stainless is corroding and the rust found a way through. It's not necessarily solid stainless steel.

Seems to me that padding is the answer.  Could you wrap it in several inches of padding to soften the blow from the landing?  Maybe try some bubble wrap, etc.

I have a bad habit of breaking bolts.  I overtightened a bolt on my motorcycle's clutch basket and broke it.  I really didn't want to deal with extracting a steel bolt from an aluminum basket, so I just left it sitting for awhile.  One night I had a dream that I went out and poked at the bolt and it just screwed right out.  It wasn't frozen at all.  The next day I went out and checked, and, sure enough, I was able to use my fingers to unscrew the bolt.  I thought that was pretty cool.

The metal sheets are a part of the safety protocol on a construction site. The prevent accidents and injuries caused to general public due to activities on site. Most of the machines and processes are dangerous.

Because it's a reactive form of metal and can easily form compounds. You wouldn't want a material in your body that's reactive otherwise you will be looking for more trouble.

Ok, you have lots of concepts.  1st, alloys are mixtures of metals, not a metal.  Second, you listed a bunch of different kinds of strength.  Stainless steel is stronger than titanium alloys for some applications.  Titanium has a SLIGHTLY higher heat capacity.  Alluminum alloys are fairly strong as well, but it's strength by weight, not strength by volume, which is what engineers need.  Not only that, but alot of metal alloys are "strong" to the point of unusable because they're not able to be shaped.

Galvanic shock for sure. Metal against metal does not go good together! Also ask any woman who's been pregnant if during her pregnancy she tasted metal, if she says yes I bet there's fillings in her mouth.

Hardened steel cannot bend like iron, due to it's crystallic structure, if it is forced to bend, it brakes.

The best answer to this question would very long. The quick and dirty response is:\n\nCutting tools in metalwork apply a compressive force to the work piece. The compressive force overcomes the forces holding the atoms together and and the material begins to slip along planes of irregular crystal stucture. The effected zone is reffered to as the shear zone. \n\nAgain this is short answer. Probably raised more questions than it answered.

I doubt that just overfilling the transmission could have caused a metal-to-metal noise.  Take it to a reliable transmission shop and have it checked out.  There may be a much cheaper solution than changing out the transmission.

it cannot be compressed therefore it shatters or cleaves

It's quite possible that you will end up with a diamond-shaped dimple in both the hammer and the anvil, because diamond is harder which means that the iron will deform first.  However, "hard" can also be "brittle", and the diamond might break into a few pieces.  The iron is most unlikely to do this, because "softer" can still be "tougher".

Force exerted on a material can cause stress and strain.  If you apply hand "pressure" to a glob of J-ello it will cause "stress" and deformation "strain."  If you set a weight on a surface, the force of the weight will cause "compressive stress" as it compresses the molecules of the surface that must strain slightly to bear the added force.  If you suspend a heavy magnet from a steel surface it causes "tensile stress" from tension that causes slight strain in the surface to support it.\n\nIf you take say a one square inch rod and press it down against a surface with a force of 100 pounds, the stress in the rod will be 100 PSI (pounds per square inch) compression and the stress on the surface will also be 100 PSI compression.  However, the force within the surface will become better distributed away from the contact point and the local stress at any such point will be less than 100 PSI.  Therefore, the cause and effect are both measured in PSI but depend for value on the distribution of the stress.  Although stress is calculated or measured in PSI the area in question may be much larger or much smaller than a square inch (like driving a car 60 MPH regardless of how long the trip is?).  Hope that helps a little.

No dents unles you hit the ball real bad, but it has between 380 and 422 dimples

I'm a metallurgist - weld material is more highly 'strained' than the parent material, so it is more prone to acidic corrosion relative to the parent material.\n\nThere is another possibility:  how do know the "weld metal" was the same as the parent material?  Perhaps the weld material was had fewer alloying elements so corroded sooner...  (cheap filler metal)\n\nOne more thing to consider:  if the part was hooked up to any electrical source, the corrosion could be caused by electrolysis rather than acidic corrosion (no kidding! happens more than you think).  Check with a voltmeter to ground; I've had batteries just eat right through stainless over a weekend; if so, insulate!
