you are really good! thank god. finally i found it before my mechanical exam

[@michaelmadrigal5628]

Very informative and not too fast. Thank you.

Is NA always horizontal? How can we know by looking at the figure on the right?

[@murtajaacademy5907]

No It can also be vertical. Depending on the moment generated due to the applied external loads.

[@uncledrew5957]

ı think d should be 5mm for I2

Why don't you keep going... You are not very fast, this is good and your knowledge transfering is very good also,

[@dudiek12]

Why are you calculating a bending moment at cross section B only? Shouldnt the biggest bending moment be somewhere in the middle of B and C? Shouldnt we supposed to calculate in a portion between B and C?
