Welcome, and thanks for joining me in Mechanics of Materials part III,

on the topic of beam bending.

The learning outcomes for today's class are to describe the importance of studying

mechanics of materials, outline the general analysis approach and

to list the major topics in the course.

Mechanics materials are the foundation for all structural and

machine design and we start with an engineering structure.

In this case, in this course,

we'll be looking at structures like bridges that contain beams.

Those beams will be subjected to external loads and, in my first course, looked

at axial loading, in part two, we looked at torsional or twisting loading, and

now in this course we're going to look at transverse or flexual, or bending loading.

And once we put those loads on the beam,

it's going to generate internal forces in moments.

That'll again, generate stresses and strains and

we can analyze those to look at the overall structural performance of

the beam to determine whether the design is successful or if it fails.

This was my first course, Mechanics of Materials part one,

in this four part series, and in that course,

we covered the fundamentals of stress and strain, and axial loading.

And you will need that course as a prerequisite before you can do this course

successfully.

The second course was on Thin-Walled Pressure Vessels and Torsion, and

that's actually not a prerequisite for this current course.

You can jump right from Mechanics and Materials One To Mechanics of

Materials III in which we're going to discuss beam bending.

And then finally, the last part IV of this series of mechanics materials courses,

we'll cover some other topics on defluction, buckling, combined loading and

failure theories.

As with my other courses in this series my emphasis is going to

be on understanding the principles A mechanics

materials rather than on extensive computational computer work.

There are lots of computer programs out there,

lots of computational programs out there that will assist you and

work with you on how to design beams and analyze beams.

But we're going to look at the fundamentals and

the principles of how mechanics and materials theory is developed and used.

And so I'm looking forward to getting started with you and

we'll see you at module two.
