Hi guys:
today I learned in class that if you have two members that you wish to joint together, that each of them will experience a force away from each other. A bolt is there to prevent them from moving apart.
however, that's the obvious part, what get my confused is that, how exactly does preloading (tightening up the bolts) help reduce the tension force in the bolts? If i do a 3rd law from the applied force and trace it all the way down the bolt, forces exert on the bolt should still be the same be there preloading or not! if anything it should have higher stress!
I am not seeing it visually, please help~~
thanks
