Welcome to Mechanics of Materials part two.

This is a course on thin walled pressure vessels and torsion.

Today's learning outcomes are to again describe the importance of studying

mechanics and materials, to outline the general analysis approach, and

to list the major topics in the course.

First, again, let's look at the engineering mechanics,

engineering science, and how they fit into the overall schematic of engineering.

So we take math, basic sciences, physics, or how the physical world works.

And the engineering mechanics or engineering science courses that you're

taking with me, are to bridge to the engineering topics such as the ones

shown here where we take an application of the science to fulfill a human need.

And this again is a schematic you've seen before, it shows where deformable bodies

fit in to the overall coursework that I've offered in engineering mechanics.

So as I've said in my first course in this series,

mechanics of materials is a foundation for all structural and machine design.

So we start with an engineering structure, in this case since we're talking about

thin-walled pressure vessel distortion, here's a thin-walled pressure vessel.

We´re going to apply some external loads to it.

Those loads could be a combination of the ones shown here, or

any individual ones shown here.

Pressure is the one that we´re looking at for thin walled pressure vessel.

And so once we have those we´re going to model it,

look at the internal forces in moments that are generated.

They're going to cause some stresses and strains in the structure, and we can

analyze those to look at the structural performance to determine whether

the structure is going to succeed or fail in what it is supposed to accomplish.

So, as a review, these were the topics that we studied in

the fundamentals of stress and strains, the first course in this series.

Now we're looking at thin walled pressure vessels and torsion and

we'll study each of the topics here.

The next course will be on beam bending.

The last course will be on deflection, buckling, combined loading, and

failiure theories.

And so as in my previous courses, my emphasis is going to be on the principal

of mechanics materials rather than extensive computation or computer work.

Computational computer work is important in these disciplines, but

I want you to have a very solid foundation of the basics.

And so let's go ahead and get started.
