I have a HSS 6x6x1/4in steel square tube that is 63.5in long. I am trying to determine its maximum load when standing vertically on end (assume it is perfectly vertical and fixed at both ends).
I have calculated the following:
Moment of Inertia = 28.6in^4
radius of gyration = 2.34in
Cross sectional area = 5.75in^2
Modulus of elasticity = 29,000ksi
I then used the formula,
Pcr= (∏^2)*(E)(I)/(.5L)^2
when i do this though I get an answer near 7,000kips or 7,000,000 lbs! there's no way that can be right and i was wondering if anyone could help me figure this out! Thanks in advance!
