Hi Clayton! For cases in which distributed loads are included, can we solve the distributed load first and combine it into one force then solve for the rest?

Great question but unfortunately no, you cannot treat the distributed load as a point load when sketching the diagrams. You will need to convert the distributed load into a point load to solve the support reactions and internal force equations but when sketching the diagrams you will see that the shear profile is directly influenced by the geometric order of the distributed load so the shape of the distributed load needs to be incorporated into the sketch (e.g. a linear distributed load results in a quadrating shear profile but a point load results in a constant shear profile so they will be different). This is explained more in the next video :) Tough question to explain through typing but hopefully this helps :P

is the axial force the same throughout the beam or does it vary with the location

It can definitely vary throughout the beam in certain scenarios but for flexure beam applications it is *typically* constant (and equal to zero), hence why we don't make axial load diagrams. A good example where it would come into play would be frames. Hope this helps!

Also Can you analyze the left side of the diagrams or not? Shouldn't it give the same answer?

You can analyze whatever side you want as, yes, it will give the same answer.
