Anyone able to help with the correct acceleration formula for this problem, like Carlo, i used Newtons second law which ended up giving me 451.19J, more than the work done value so incorrect.
What a plonker i am, i have been doing 0.08 x10^4 instead of 0.08^4 .. Can you tell i have just started studying again since school.
Thanks SteamKing - look out for more amateurish questions coming your way..haha.
Homework Statement
Question is about buckling, so i know i need to work out I (moment of Inertia), which is for a hollow tube.
Homework Equations
So the paper states..I = (0.08^4 - 0.06^4)∏/64 = 1.37 x 10^-6 m4
When i do that on my calculator, i don't get this answer. Puzzled...
