You can demolish a stone wall with a sledgehammer, and it's fairly easy to level a five-story building using excavators and wrecking balls. But when you need to bring down a massive structure, say a 20-storyskyscraper, you have to haul out the big guns. Explosive demolition is the pref...
This step-by-step guide covers how to replace a car fuse. From locating fuse boxes to safely swapping blown fuses, master this basic DIY maintenance task.
The body is fused together with the engine and wings, creating one lifting surface. This lightweight design allows the flying wing to use 25 percent less fuel than a 747. Image courtesy NASA Passenger bays - The aircraft will carry 800 passengers in a double-deck cabin that is divided ...
If you find a rough spot, you may be able to smooth it with an emery board or light sandpaper. If this doesn't work -- or if you have to cut to bare metal to remove the roughness -- the tub should be replaced. In this case, it's probably much wiser to replace the entire ...
Finally, connect the hardwire kit’s power cable to the dash cam. Step6: Test the Hardwired Installation Start your car and check if the dash cam powers on and starts recording. Most dash cams will indicate they are powered on with a light or voice alert. Use the app to verify the co...
Aviation loves additive manufacturing, largely due to the promise of lightweight and stronger structures offered by 3D printing. We’ve seen a whole bunch of innovations in the domain of aviation lately, with the appearance of more critical parts being printed....
To keep the heating element from overheating, there are also components such as sensors and fuses. In coffee makers, sensors detect if the coil is getting too hot and cut off the current. Then, when it cools down, they turn the current back on. By cycling on and off like this, they ...
How to Build Your Everything Really Really Fast: A few years ago, I wrote a short document on methods for rapidly fabricating elements of mechanical systems entitled How to Build Your Robot Really Really Fast. It was catered towards students in MIT's 2.0
A myriad of electrical gremlins can come to light with a car’s age—bad terminals, broken wires, blown fuses, and even fried relays. Knowing how to diagnose those problems can be the difference between staring hopelessly under your hood while uttering some choice four-letter words and actually...
Take the simple case of an electric light. Two wires connect to the light. For electrons to do their job in producing light, there must be a complete circuit so they can flow through the light bulb and then back out. The diagram above shows a simple circuit of a flashlight with a batt...
