What is Proof Load of Bolts? - Engineering Stack Exchange
Mar 23, 2021 · Shigley's Mechanical Engineering Design textbook states that, "proof load is the maximum load (force) that a bolt can withstand without acquiring a permanent set". Other sources …
Can someone help explain the difference between strength and stiffness?
Jan 9, 2024 · The strength definition here is technically "yield strength". There is also "ultimate tensile strength" which is the amount of load that will break the material.
Beam of uniform strength - Engineering Stack Exchange
Feb 14, 2022 · Even though I get why they are called fully stressed beams, I don't understand why they are called beams of uniform strength. Strength to my understanding is the capability of a structure to …
Why 0.2% of strain is considered while taking proof stress?
May 22, 2016 · The 0.5 % total strain ( 0.2 % permanent strain) is a good number for most metals and is widely defined as the yield strength. It is a problem for high strength steels so API defines the yield …
