Sections
Shear forces and bending moments aren’t diﬃcult, as long as you got an easy method to calculate them.
In this chapter I just explain a method. Use it if you ﬁnd it handy, and otherwise just use the method
you’re used to.

Chapter 6: Analysis of Structures
Some of the most common structures we see around us are buildings & bridges. In addition to these,
one can also classify a lot of other objects as "structures."
For instance:

Using signs: always a dicult thing
When youre calculating all kinds of formulas, theres always the matter whether to substract values from
eachother, or to add them up. There is a method which saves you that trouble, which works in normal

Virtual Work
Virtual work, if mastered well, can make it very easy to solve certain problems. While normal solving
methods can involve numerous calculations, virtual work sometimes enables you to solve a problem with
just one equation, and thats the benet

Denition list
Two-force member - An object (like a rope, or a bar) on which two forces are acting. Both forces
have the same magnitude, but opposite directions. These forces seem to cancel eachother, but they
work on dierent positions
Truss structures and frames
Truss structures can be incredibly dicult things to handle, and the only way to be able to handle them
well, is to practice a lot. But were going to try to state some general things about them anyway.

Previously we found that a system of forces can be reduced to a force-couple
system.
When the force and couple are equal to zero, the body is said to be in equil
