Inside the barrel of the cannon is an empty cylinder, into which the performer climbs. This cylinder acts as a sled of sorts. When it fires, the cannon pushes the sled forward at a force of 3,000 to 6,000 pounds per square inch (psi) of pressure [source: New York Times]. The ...
On a standard clincher, the overhang hook and tire bead interface keep the tire on the rim. Tubeless-ready tires have strong and stiff beads that create an air-tight seal between the rim and tire. The tire relies on the stiffness of the tire bead to keep it attached. When putting on ...
The pop-off valve is simply a plate held in place by a strong spring. When too much pressure develops in the manifold, it pushes the plate up to release the pressure. The manifold and valve in Motorola's car Pop-off valves are now electronic. When they release, they are loud enough...
Plywood is a strong laminate composed of several thin layers of heavily compressed wood glued together. Some people consider it to be inferior to standard lumber, but the opposite is almost always true. A quality piece of plywood is typically stronger than the corresponding amount of standard wood...
carbon atoms, forming atetrahedralunit. This tetrahedral bonding of five carbon atoms forms an incredibly strong molecule. Graphite, another form of carbon, isn't as strong as diamond because the carbon atoms in graphite link together in rings, where each atom is only linked to one other atom...
Once an earthbag home is complete, you would never guess that the walls are made of dirt. The walls are strong enough to hang cabinets and pictures, and plumbing and electricity are installed just as in a conventional home. Lofts can provide extra space. Earthbag builders Kaki Hunter and Don...
These problems are likely to result if the carbon dioxide regulator is improperly set. The pressure you need will dependent on the type of beer you use, but many beers require about 12 psi to maintain a strong and consistent draft. For more information on kegerators, pouring and brewing ...
While storing mechanical energy in the spring is a lightweight method to achieve a strong, fast grasp, it requires a re-opening mechanism capable of initially loading the claw and secondly releasing the grasp from the branch after perching. Whereas closing the claw needs to be a fast motion,...
equivalent to 500–1000 wind turbines working at full capacity). In the biggest turbines, in large fossil-fuel power plants, the steam pressure can be as high as 20–30MPa (3000–4000 psi or about 200–270 times atmospheric pressure). A small, 10 megawatt steam turbine is roughly the sam...
PSI is often used to classify the pressure washer as a light duty pressure washer or a heavy duty pressure washer —where the actual dividing line lies is subjective to the brand. Generally speaking, light duty washers have 1800 PSI or less, while heavy duty washers have 2800 or higher PSI...
