Hi, I am a final year student whos doing engineering and my final year project involves designing a track system which the track has an axial and vertical loading(twisting) to it, well the axial loading is caused by the vertical loading. I have limited resources and need to pick aluminium alloys from different cross-sections. The thing is how do i analyse different cross-sections providing they are gonna be quite different? Or any books recommend for me to have a look at? Thank you, Kent Zhou.
