Bolt dimensions In plate bending

AI Thread Summary
The discussion focuses on calculating shear forces in bolts connected to a plate experiencing bending under load. The user seeks to minimize bolt diameter while understanding the relationship between shear forces in the plate and the bolts. They express uncertainty about how to derive shear stress in the bolts when the applied force is perpendicular to the plate. The user is familiar with estimating bolt dimensions based on shear force but needs guidance on calculating the force acting on the bolts from the vertical load applied to the plate. This inquiry highlights the complexities of analyzing bolt dimensions in plate bending scenarios.

Hey

I have this plate, and as you can see it has 4 bolt connections and no other. When applying the load bending will occur in the plate. I am interested in making the diameter of bolt as small as possible. My problem is though that I only can see the shear forces in the plate.

How can I find the shear forces in the bolts ? (I guess these forces will be equal of the normal forces in the plate ??)

I am familiar with estimating bolt dimensions using shear force, but I am looking for a way to find the shear stress in the bolts, when in this case the applied force is perpendicular to the plate, hence in same direction as the bolts ...

Hi

It is exactly that case I would like to calculate, but the thing is that I have to estimate the force P (from this example) from the force that I apply vertical on the plate (and not in the shear direction as in the example).
 
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 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
