Homework Statement
this is a picture of an example from the book. I am going off of it to solve a problem that will be on my test tomorrow. i can figure out how to calculate the shear force and moment of each section (though i don't fully understand it), but I am just not getting how they decide on these sections. sorry for the crappy photo, all i have it my camera phone.
the sections are labeled like 0<x<4, 4<x<8 etc. but when they draw the 4<x<8 section in the example they include the 0<x<4 section...? why? and how come x changes with every section. that's confusing the hell outta me. oh and on the first section diagram to the left, how did they come up with (x/4)*100? and 12.5x^2?
thanx
