3. A 5.0 meter tall steel column with a rectangular cross section of 100mm by 80mm has fixed ends and is subjected to a vertical load P = 500kN. Using a safety factor of n = 2.5, let oyp = 280 MPa, E = 200 GPa, determine (a) the critical load and critical Euler stress, and (b) based on part (a) will the column fail by yielding or buckling? How do you know?

I need answers to questions 1, 2, and 3 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.

I need parts 4, 5, and 6 answered pertaining to the print provided.

Last person got every single question wrong and didn't include units. Please help.

The class I'm taking is physics for scientists and engineers! **** I need help with part  D only*****  Can you please write out the solution and not type out the solution? I had to reask this question because the last tutor typed out the solution and it was very hard for me to follow . Please and thank you for the special request. I have attached the problem.
