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.
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
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...
