Hi,
I have a question from an engineering science assignment that I'm stuck on.
1. Select the lightest wide flange section that can be used as a steel column 7 m long tosupport an axial load of 450 kN with a factor of safety of 3. Use 200 MPa as the limit of elasticity, 200 GPa as the modulus of elasticity and assume that the column is simply supported.
I have a printout with my assignment of universal columns dimensions and properties. As part of this printout I have the final answer on a answer sheet = Second moment of area, I = 3351 cm^4.
Im not sure if I need to work out bending moments and bending stresses, or if there is a formula to work this out using the figures I have been given.
I have looked in my textbook for this, however as I'm slowly finding out my textbook is not brilliant.
If anyone can help or knows of any good tutorial websites for this it would be a big help.
Thanks
Emma
