Shear stress on bolts (in different planes)

AI Thread Summary
When shear force acts on bolts in two different planes simultaneously, each bolt does not share the shear force equally; rather, each bolt experiences the total force (F). In cases where bolts are arranged in the same plane, they develop individual reaction shear forces. The discussion emphasizes that bolts do not support shear on their shank, as shear is primarily carried through friction in the joint. It is important to ensure that the bolt shank does not touch the edges of the hole to maintain proper load distribution. Understanding these principles is crucial for accurate bolt design and analysis.

I am trying to understand the behavior of bolt in different
plane.

My doubt is when shear force acts on bolts in 2 different
plane simultaneously, does it share the shear force (F/2) or
each bolts experience the total force (F).

I am sure that if there is a bolt pattern on the same plane,
each bolt will contribute (develop individual reaction shear force).

Please find the attachment.

What you have drawn looks like a rod through a block. In this case, assuming perfect symmetry, the shear on each side should be F/2 assuming that each end is supported in the same manner.

It really is not a bolt problem because bolts don't support shear on the bolt shank, but rather the shear is carried on friction in the joint. It is common to calculate bolts to see if the shank section will support the shear load, but the bolt shank should not even touch the edges of the hole.

Thank you Dr.D. I got it.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'What type of toilet do I have?'
I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...
