I'm working my way through the eighth edition of "Simplified Design of
Steel Structures" by Ambrose and Tripeny (Parker having died at some
point), and I'm finding it to be an odd mix of very basic definitions
and material that requires substantial background. In the latter
category, they've suddenly launched into shear and moment diagrams
with no explanation of just what the diagram is visualizing.

Can somebody point me at a good source for this?

Pick a college statics text from about the same era as your book?

I don't have my statics book anymore or I'd cite it. It was a good one.

Trailers: How to Design and Build vol. 2 structure explains moment
diagrams if your library has a copy. If not it is a nice book for the
home library.

BTW its author is M.M. Smith

This looks like a good explanation.

Thanks to all who've responded so far -- lots of good information out
there. Especially good is a link from the roymech site to
http://ocw.mit.edu/NR/rdonlyres/Mate.../0/statics.pdf
Looks like this latter is part of a course....

You like that book? Most of the Amazon reviews give it one star and
review it quite harshly. I decided not to buy it because of them.

The shear diagram is deisgned to help visuallize the total forces on a beam,
which are sometimes not obvious. The moment diagram helps visualize the
magnatide and location of the bending moment on the beam. The maximum
moment (and therefore the maximum bending stress) is located where the shear
diagram changes sign. The power of the diagrams comes when you have several
externally applied forces and moments on a beam.

People think that it is going to have trailer designs in it. It doesnt.
But it does tell you how to design a trailer and what forces are acting
on it. But it also has a bit of higher math in it. I think that is why
people give it a bad review.
