We await enlightenment.
Looks like a proper test is in order and until then we will agree to disagree. I think it will show significant damage and you don't. I can say that laying your hand on a spinning disc brake isn't going to cause the same damage as smacking that hand into it with force.
For instance, I have a cleaver used to chop up meat. I can rest that cleaver on my hand and nothing will happen but if I slam it into my hand with force it will cut my hand off. I'm sure there is enough internet engineering in this forum that we can delve deeply into why that is for a few pages, but I will leave it at that.
