Metal tensile strength question

AI Thread Summary
To determine the force required to bend a 1/4" thick 304 stainless steel "L" shaped piece beyond 90 degrees, one must analyze the tensile strength and shearing forces of the material. The area of the bent section is estimated to be 2" x 1/2". Calculating the average shearing force based on this area and the material's tensile properties is essential. The inquiry seeks a specific force measurement in pounds needed to achieve a 100-degree bend. Accurate calculations and engineering principles are necessary for a precise answer.

I have some 1/4" thick 304 stainless steel formed in a 90 degree "L" shape (2 1/4" up x 2" flat x 2" wide. What force is required to bend pc beyound 90 degree mark (let's say to the 100 degree mark)

Analyze the tensile strength or stress of your stainless steel : http://en.wikipedia.org/wiki/Ultimate_tensile_strength

Having found this , you now the area of "L" shaped steel. You can obtain shearing force also : http://en.wikipedia.org/wiki/Stress_(mechanics)

Analyze the values for shearing forces and then average them...

I would estimate the area of material that is bent is approximately 2" x 1/2". I went to the tensile chart but could not figure out what the pc I have in question would require to be bent. Would like the answer to be described as follows: It would take ___ lbs of force to bend the described pc.
 
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...
