Please help, URGENT Hi guys, Sorry if I’m posting In the wrong place, I’m a newiee:D I have a problem (seriously, it is not homework), no equations, no numbers, just a mechanical question. I’m trying to break a rod for instance (The rod has the same diameter althrough except for one point where it becomes thinner). I know where it will break since it is a little thinner or weaker in a part of it. Now, I put it on a holding device put force on exactly adjacent to the weak line (where the thin line is). Is the amount of force required to fracture the same rod going to change, by changing where the holding device is going to grip the rod? (I made a picture of the situation) Thank you in advance. Please guys, i've been checking this post 10 times every hour!!
