How Does It Works Driveshaft

What it is and how a Drive-shaft works??? A drive-shaft is a mechanical component, one of the most important car parts for transmitting torque and rotation. This mechanical component is usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them. The video below is a perfect demonstration of the drive shaft working principles! So, watch the video now!


How They Work. Disc Brakes

A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc. This is how friction is created, so this action retards the rotation of a shaft, such as a vehicle axle to reduce its rotational speed or to hold it. The most commonly used form of brakes for motor vehicles are the hydraulically actuated disc brakes. The main components of a disk brakes are the brake pads, caliper, caliper support, rotor. Watch the video below to find out more about disc brakes!


The Thorium Powered Vehicles. No Need Of Fuel

Great news – no more need of refueling your cars! New, more efficient technologies are waiting to be unleashed and  thorium seems to be one at the top of the list. The Laser Power Systems company has been working on creating an emissions free turbine/electric generator powered by nuclear thorium lasers. Yes, thorium is a nuclear fuel! Charles Stevens, CEO of this company claims that one gram of thorium yields the energy of 7,500 gallons of gasoline so, the energy is harnessed by heating the thorium with an external source.  The Thorium is safe and a very clear source of power.


HOW TO MAKE A SAW POWERED BY A DRILL

What's it for:
A corded power drill is used for drilling holes in metal, plastics, wood, brick, stone, concrete, glass, and tiles. Various types and lengths of drill bits are available depending on the material being drilled; HSS (High Speed Steel) bits for metal, flat bits for wood, and masonry bits for concrete.

How it works:
The bit is held in a clamping device on the end of the drill shaft called a chuck. Some drills come with chucks which are keyless and can be hand-tightened, others are fitted with chucks which need to be tightened with a chuck key. This allows the drill bit to be tightened more securely and large bits are less likely to slip, but keyless hand-tightening chucks are more convenient. Most DIY model drills will have a 1/2 inch (13mm) chuck which can accommodate drills up to this diameter, but 5/8 inch (16mm) chucks are also available. These drills range in power from about 500 to 800 watt. 650 to 700 watt provides adequate power for most jobs.

If you need to drill holes in awkward spots, you can get a right angled chuck adapter which fits into the chuck of the drill. Alternatively flexible drives are available.

A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water.



FIGHT FOR SURVIVAL shocking moment dying polar bear

FIGHT FOR SURVIVAL shocking moment dying polar bear desperately searches for food on barren landscape

Paul Nicklen, 49, filmed the soul-crushing encounter that saw the adult male desperately trying to satisfy his hunger by chewing on a snowmobile seat after rummaging through a bin.

SeaLegacy, a non-profit social enterprise was filming for five hours as the emaciated polar bear struggled to find food on Somerset Island in Nunavut, Canada.

With no wounds on its body, and not old enough to die of old age, it’s not known exactly what happened to him but he is feared to have died.

During summer the bears can go for several months without eating while they wait for the Arctic Ice to solidify but because the ice is freezing later and melting earlier, their fasting period is prolonged.


How to Make a Generator that Runs on Wood

When wood is heated it releases a few different types of flammable gases, I use a homemade gasifier to extract these gases out of the wood, I first run the gas through a condenser coil to condense any steam and tar out of the gas, I then use a bubble filter to catch that water and tar and it also helps in filtering out some of the unwanted smoke, next the gas runs through a homemade filter to remove the last of the unwanted byproducts, The wood gas then runs directly into the air intake on the 25cc engine.
This was only my first test. It seems the wood was a bit wet and I also didn't let the gasifier stay hot long enough, this caused the gas production to be very inconsistent and the engine to only run for a few minutes at a time.
I will do a second test at some point, subscribe so you don't miss it.
Thanks for watching :)
