Statics & Mechanics
Statics and Mechanics are the basics of structural engineering.
What are its principles, how is it used in the design, and what are real-world structural examples?

Let’s have a look…
Principles
Step #1
Do you know whether the static system is statically determined or indeterminate?
Step #4
If you don’t know what internal forces are, its sign convention or how to calculate them, read this step-by-step article.
Now it’s time to apply the knowledge to some examples …
INTERNAL FORCE CALCULATION
Here Are Some Examples
Simply supported beam, cantilever, and arch.
We definitely need to know how to calculate reaction &
internal forces, but at some point in our studies or career
formula cheat sheets are very helpful.
Check them out.
