Engineers run the world
Is it possible to have a successful board about engineering?
MARBLE MUSIC MACHINE
Because it's awesome.
'Sup, /eng/, I'm in need of help from the mathematically inclined.
I want to make iron plates for lifting exercises.
The dimensions are as follows:
>450 mm diameter of the plate
>34 mm diameter of the hole in the middle of the plate
Now, according to the known information, what would be the other dimensions of the plates with varying weight given that the above dimensions cannot be changed.
For a:
>25 kg plate
>20 kg plate
>15 kg plate
>10 kg plate
>5 kg plate
>2.5 kg plate
Thanks in advance.

"We want to set the bar so high that it will be very difficult for anyone to take, it," project director Richard Noble told AFP.
>Beating the record is a big motivator for the team but is not an end in itself—their aim is also to give a taste for science to a new generation.
>"We had a meeting with the Ministry of Defence and they said we have a terrible problem—we can't recruit scientist engineers," Noble said.
>"In the US during 1961 to 1972, the number of PhD achieved in science education increased by 300 percent" because of the space race between the United States and the Soviet Union, he said.

This guys channel is great. Tons of weird home projects and some excellent tool reviews
Engineering Disasters
Engineering is dangerous and serious accidents happen. As engineers it's our responsibility to learn from those accidents and make sure that they never happen again.
It's good to share videos and stories of engineering failure.
Piper Alpha 1988
>Piper Alpha was a North Sea oil production platform operated by Occidental Petroleum (Caledonia) Ltd. The platform began production in 1976, first as an oil platform and then later converted to gas production. An explosion and the resulting oil and gas fires destroyed it on 6 July 1988, killing 167 men, with only 61 survivors. The death toll included two crewmen of a rescue vessel. The total insured loss was about £1.7 billion
There are two videos I recommend watching about this incident.
There is a technical presentation by Brian Appleton (Technical adviser to the accident enquiry)

National Geographic - Seconds From Disaster. Lots of computer graphics, interviews and exciting TV drama.

I watched the technical presentation before the National Geographic episode and I enjoyed it.
Engineering News
I suppose a thread for engineering news makes sense so here you have it.
MEDIA GOES HERE
Dumping engineering awesomeness.
Hyundai and their ship building facilities. They're world leaders and it looks like they're setting the bar high.
Hello /eng/
i'm going to study Electrical and Communication engineering next year but i'm really confused about it and i want to know more about it like what are the fields that i can work in it and the Job opportunities specially abroad
Hey /eng/
I'm a high school /eng/ineering student and I'm struggling. It's really interesting, but I'd also like to, well, do well.
Are there any textbooks that can help me/general info? PDFs preferred
Ball Mill Project
I wanted to build a little ball mill years ago. I didn't get very far then forgot about it.Now I've remembered it I'm going to have another go at it and document it here.
I made the crappy Solidworks model after knocking together a crappy "prototype" with a few things I had lying around.
The plan is to drive the drum with a wheel with the drum encased in rollers at a rate of approximately 65 RPM.
I'm a little rusty because I've taken some time away from university and haven't done anything since. I'm quickly giving myself a headache doing even the most simple things.
Hey folks, I am working on a senior design project in civil engineering. I got stuck doing the structure of the project despite not knowing a whole lot about it. I am currently looking at wind loading and it just baffles me. Anyone have any experience?

Favorite Subdiscipline
We can argue all day and night about best engineering field but what's your favorite area of study in your field?I'm a mechanical engineer and I love mechatronics. I always thought electric motors were really cool and they're an inexpensive way to fuck around with side-projects.
I know there are some alternative reactor designs to tokamak, stellerator and initial confinement.
One simple setup to create nuclear fusion is a fusor. You have two spherical metal grids. The inner one is charged negative. The outer one positive. Then you ionize hydrogen isotopes in between those spheres and the protons get accelerated towards the middle, where they hit. It is easy to reach the energy levels for fusion with this setup. However as many protons are lost in the grid it can not be used for power production. It is however used as a neutron source.
A concept to build a power producing variant is to replace the inner electrode by a cloud of electrons confined by a magnetic field. That is called a polywell.
Does anybody have some good resources on polywell research or on other alternative reactor designs?
Project Hotwheels
A collaborative effort to create a fully functional design, from the ground up, for something to help disabled people.People in wheelchairs can get cold and often have difficulties doing things. I think having hot drinks on tap would be a nice thing.
Idea #2: Cripple Golf. Golf cart/chair with a golf ball mortar.
wind turbines
I was going to build a to scale wind turbine, but I can't seem to find key information about their dimensions, specifically about the blades, even more specifically about their airfoils. How many do they have? What is the size difference between those in different locations?
