For these types of question, I know deflection equation is needed to find the reaction.
However, my question is that when should i use the max. deflection equation and when should i use only simple deflection equation for my calculation ?
Thank you very much!
I am calculating the all reaction forces in this beam.
However, I want to ask:
By taking moment about point B, why does the moment of the UDL become 15*7*5.5 instead of 15*7*4.5
Thanks !
