Bolt Bending?

10/17/2009 4:38 PM

I am a Mechanical Engineering student working on a project and I have a question concerning a bolt in a joint. The rod ends are connected to members that will be in tension, so they will obviously apply a load to the 3/8" bolt at their point of intersection with the bolt. I have analyzed the bolt for double shear. Do I need to consider bending stress in this bolt due to the fact that the points of intersection of the bolt and rod ends are not directly next to the alum. angle? Thank you in advance for any replies, I really appreciate it!

Your bolt is loaded with:

- an axial force from the rods which is force in the rod*sin(20°)

- a transverse force force in the rod*cos(20°)

- the preloading force has to be computed accordingly

So that you are confronted with a complex load in shear+tension at same time so that you should use the adecuate resistance hypothesis for it.
