For a test, I loaded some SS 304 parts and found that they didn't yield at 50 lbs and did yield at 75 lbs. Therefore, I only know the yield strength is between 50 and 75 lbs.
A customer has returned some parts (same design as above). The parts hadn't failed but they have plastically deformed...
We have a 302 SS compression spring that rides inside a borosilicate glass (Pyrex) tube. The wire dia is about .025 and the spring force is nominally 1 lb.
After about 250,000 cycles of the spring, it appears the spring is rusting on the OD where it rubs on the glass. The environment is room...
In a recent thread (thread378-122965), someone presented anecdotal evidence that leaks in compressed air lines allow humid air from the factory to enter the air lines. This of course caused a problem with wet air downstream of the leaks.
Can this possibly be true?
How can the low pressure...
I'm interested in the spring rate of a cantilevered beam (one end free, one end fixed). I've rearranged the formula from Roark's to be:
Spring Rate=3EI/(length^3) for a=0 (load at free end).
OK, now what I don't know is what happens when there is an axial compressive load in addition to the...
