From the US Naval Research Laboratory manual Mechanical Practice.

There’s also a *great* diagram of Phillips-head screws.

Thus do we master the physical world.

From Mechanical Engineering, a journal published by the American Society of Mechanical Engineers in 1919.

Not the moving parts kind, but the wedge/screw/lever kind. Want to move giant blocks of stone a few miles, but the locomotive and crane haven’t been invented yet? Nature‘s answer… by waiting until winter and freezing the streets:

Some of the largest stones used to construct Beijing’s Forbidden City beginning in 1406 were hauled from distant quarries on wooden [...]

I’ve seen this in a few different venues, but Laughing Squid brings the best of it together. A dad, frustrated at the thought of buying his son a prosthetic hand for tens of thousands of dollars, instead figured out how to print one for about $10 in materials:

Two years ago, his father Paul McCarthy saw a video of [...]

Gigaom takes the two great tastes of home manufacturing and carbon crystalline structures and makes them taste great together with a 3D printer that creates objects out of graphene:

Mining and technology development company American Graphite Technologies announced this week that partner researchers at the Kharkov Institute of Physics in in Ukraine received final approval to begin researching [...]

Says it all right there. You want to see inside the world’s largest particle accelerator? Street View will take you into the underground tunnels:

We’re delighted that CERN opened its doors to Google Maps Street View allowing anyone, anywhere in the world to take a peek into its laboratories, control centers and its myriad underground tunnels housing cutting-edge experiments. [...]

This was all over Reddit and ScienceDaily today, because it’s cool. Biologists have found the first example of machine-like gears in a living organism, a critter called an adolescent Issus:

Through a combination of anatomical analysis and high-speed video capture of normal Issus movements, scientists from the University of Cambridge have been able to reveal these functioning natural gears [...]

People seem to like caissons (pressurized chambers used to build foundations underwater), or so my search referrals tell me.

Well, here’s what working in a caisson can do to you – give you the bends, or something like it. To avoid that, yer construction crew needs to go into a thing like this. Once they take off the deep-sea [...]

BBC has the details on the space-agency’s successful test of a printed fuel injector:

The part is used to deliver liquid oxygen and hydrogen gas to an engine’s combustion chamber.

…

NASA said that California-based Aerojet Rocketdyne had made the injector using a method called selective laser melting (SLM).

The technique involves turning a computer-designed object into a real-world part by controlling [...]
