When you say top flange can be the restraint points for the cantilever beam, is it because the position of the load being at the top flange and therefore it is driving a destabilising force? If thats the case, if the load is positioned at the bottom flange, do you still say the critical restraint points needs to be to the top flange or in this case to the bottom flange? It is known the compressive flange is prone to buckling but what is the reason it becomes the top flange when it comes to a cantilever beam? And as mentioned above, is it because of the position of the load being at top creating a destabilising load? Thank you Prof all your lectures are fantastic😊
I was lost when you say the tip of top flange is in tension in the case of downward force. Does that mean the tip of a bottom flange then carries compression?

thank you for your nice lecture on structural design course
