Choosing to be an Engineer

Hey folks!

Sorry for not posting new stuff the last few days, had a bunch of work to do!
I hope you don't mind too much.

Today I wanted to post you a video about the Job as an Engineer. It is from a university to tell the possible students what they can - and have to - expect.

I hope you watch that vid - I think it is done very well.

Have you ever thought about choosing a carreer in engineering, or technology in general?
Comment, if you like!

Have a nice day

Simulation of a bra

Hello Dear readers,
today I want to talk about the use of Finite Elements Method on ... yeah, you read right... a BRA.

The FEM is used to do a stress, flow or temperature analysis of - usually - mechanically components of a machine or something related. By dividing that component in a huge amount of small cubic or triangle elements, the stress problems can be solved.

In a graphical output, the stresses are displayed. Usually, the higher the stress, the color gets more into the reddish side.

The Video above shows such a FEM simulation done on a bra. As you can see, the areas displayed in the blue-ish colors are hardly stressed.
When talking about machine parts, every engineer is trying to save material, as it is one major cost factor in production.

So you may think, why not save material costs in BRA INDUSTRY???

Picture above is me at the beach (with my ex bf cut off, actually)... I'm actually too shy to wear more lean bras or bikinis... though I know now, that most of the cloth used is not necessary!

What do you think of that? Comment please :)

Excavator Destruction

Hello Friends,

today I want to introduce you to a real monster, the LIEBHERR R9800.

In that video above - some of you may already know it - it simply destroys a car, using nothing more than  42 tons of water.

Some data about that excavator:

Operating weight
800 - 810 tons

Engine output
2984 kW/4000 PS
(ISO 9249)

Backhoe bucket capacity
42.00 m³ @ 1.8 t/m³

Shovel capacity
42.00 m³ @ 1.8 t/m³

Some more picture (taken directly from LIEBHERR):

Controlling one of these must be great! Making you feel like in Transformers, maybe.

What do you think of it? You'd like one for christmas? ;-)

Mortal Kombat 2011

Hi Folks,

today nothing about engineering stuff as i found two stunning videos on that new MK.

Look here:

Trailer 1

Combo Moves Compilation

The Game will be released in early 2011, but only for xbox and PS.
I think it's worth buying one of these gaming consoles then, really took that into consideration!

what do you mean? are you going to buy MK 9?
Comment on that pls!

Shock resistance of Surface Coatings

This picture shows the zones of failure in an impact situation on coated surfaces.

In the peripheral zone there are the well-known bending-cracks, caused by the stretching of the substrate layer during the plastical deformation caused by the indenter.

In the central zone, the coating material cracks cohesively, thus causing irregular crack structures. This zone is especially large for brittle coating materials, such as (Di-)Chrome Nitride.

The zone in between shows failure of both types mentioned above.

To clear things up: this is sort of the things that make your saws, knifes and razors blunt.

Topic of research is to develop coatings that are very resistant against this kind of wear, as well as against abrasive wear, to keep the perfect quality of the surface for a longer time, thus keeping knifes sharp much longer.

I do really hope to enlighten things a bit. Comment on this, if you like.
Also, tell my your criticism,
what kind of topics would you like me to talk about next time?

Mobile Cranes

Now a little Teaser to LIEBHERR Mobile Cranse as they can be seen regularly on many construction sites.

The pictures above show the crane "LIEBHERR LTM 11200-9.1". It is the strongest telescope crane in the world atm.
It can lift up to 1200 tons up to 100m height. With an additional spire construction, even up to 226m height.
It is powered by a 500 kW Diesel Engine for driving and a 270 kW Diesel Engine for lifting.

With its 9 axes and 1.50m high wheels it reaches a top speed of 75 km / h.

The attached videos show a Diashow of that crane.

Video 1 @ youtube
Video 2 @ youtube

btw: I very much like the song in the second video :-)

Feel free to comment on this topic, the song or the pictures!
