AI Thread Summary
Information on screws classified as A4 is limited, particularly regarding tensile strength data. The discussion references the need to replace terms like "strength class" with "ISO property class" for clarity. It highlights the importance of understanding ISO steel grades, specifically A2 with property classes 50, 70, and 80. Users are encouraged to consult resources like RoyMech for detailed specifications. Overall, the conversation emphasizes the need for accurate terminology and reliable data on screw classifications.

Hi All,

I am reading about screws and screw classes, but can not find any data (such as tensile strength) on screws with the class A4...Best Regards,

See roymech[/color], except change "strength class" or "strength designation" to "ISO property class," change "Newton" to "Newton," and change N/mm^2 to MPa. You can also see ISO steel grade A2, property class 50, 70, and 80 (i.e., A2-50, A2-70, and A2-80) here[/color].
 
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'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
