What is the Maximum Torque Needed for Failure of a Serrated Plate with 48 Teeth?

AI Thread Summary
To calculate the maximum torque needed for failure of a serrated plate with 48 teeth made from stainless steel, one must determine the shear force required to break a tooth. The shear force can be calculated using material properties and geometry, specifically the tensile strength of stainless steel and the dimensions of the teeth. Once the shear force per tooth is established, the total torque can be derived by multiplying this force by the radius at which the force acts. The discussion highlights the importance of understanding both the material properties and the mechanical design to accurately assess failure points. Calculating these values is essential for ensuring the integrity of the serrated plates under load.

If I had 2 serrated plates like the ones in the attached picture locked in place like seen below. How would I go about calculating the maximum amount of torque needed for failure of the part. Assuming it has 48 teeth and is made from stainless steel?

Can you determine the force needed to shear a tooth?
 
yea i guess that works too
 
Did you figure this out?

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...

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...

Thread 'Cantilever help'

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
