Hi
I want to determine the bending load limit to elastic failure of extruded aluminium square section, 50 mm sq, warious wall thickness, 1, 2, 3, 4, 5 mm
I thought I could get a good estimate from the tensile strength. I found a value of 90 Mpa for commercially pure aluminium but doubt that is the right value to use for normal garden variety extruded aluminium from the local hardware.
Also, I'm just going on what I remember from high school mechanics.
Some advice on general approach would be appreciated, just remember, with adding safety factor, it needent be to the nth degree. The application is that I'm converting a sailing dinghy cradle into a beach launching trolly and I want to keep the weight down and find what I need to order for the job.
Regards,
Ken
