Urgent Help Please!
Just want to ask some rules/ tips in drawing MOMENT DIAGRAM BY PARTS and COMPUTING FOR THE MOMENT OF THE AREA OF THE MOMENT about a particular axis.
Here's the step I typically do:
1. Get the reactions.
2. Plot the moment diagram of EVERY force. (that's why it's called by parts)
3. Take the moment of THE AREA OF THE MOMENT from (2) to either the LEFT or RIGHT end of the beam.
Here's what confuses me. In (2) , can I take the moment of the forces at ANY PART OF THE BEAM? Does the result will be the same if I take moment on OTHER PART of the beam?
Then, what is the general rule and would you give me some tips in doing this stuff. Thanks a lot! :D
