One lightning hit to the Hindenburg would have sent it into flames. And lastly the static theory build up of static electricity near the Hindenburg’s tail may have caused a fire to the hydrogen tanks. Although hydrogen burns at a blue faint flame, this theory was proven
He is responsible for creating many things which help us greatly today. In the scientific world he is mostly known for his experiments on lightning and electricity and his invention of the lighting rod. In 1750, Franklin discovered that lighting is electrical by flying a kite into a storm cloud and collecting some electrical charges. This showed that lighting was electrical and led to his invention of the lighting rod. A lighting rod is a metallic object that is mounted onto an elevated structure with the intention of diverting a lighting strike away from the structure to a safe location into the ground.
Conduit - A rigid or flexible metallic or nonmetallic raceway of circular cross section in which cables are housed for protection and to prevent burning cable from spreading flames or smoke in the event of a fire. Racks - A frame-like structure where patch panels, switches, and other network equipment are installed. The typical dimension is 19 inches. Punch-down blocks - A generic name for any cross-connect block where the individual wires in UTP are placed into a terminal groove and “punched down” with a special tool. The groove pierces the insulation and makes contact with the inner conductor.
The Strap must be attached to the top plate of the wall frame or embedded in the bond beam in at least one place. D. Double Wrap Both Metal Straps must be secured to every rafter/truss with a minimum of 3 nails, wrapping over and securing to the opposite side of the rafter/truss with a minimum of 1 nail. Each Strap must be attached to the top plate of the wall frame or embedded in the bond beam in at least one place. E. Structural Anchor bolts structurally connected or reinforced concrete roof. F. Other: G. Unknown or Unidentified H. No attic access 5.
Each crew member should have a high level of situational awareness before entering a burning building. For example, firefighters need to be able to read fire behavior indicators, understand the crews tactical assessment, know probable emergency escape routes, know forcible entry requirements, identify hazards, and verify that radios and properly working. When containing fires, firefighters also need to remember vital aspects like gas cooling is not a fire extinguishment method but rather a way of reducing the hazards presented by the hot gas layer or that the most effective use of water on free-burning fires is made with direct attack on the fire. If a firefighter cannot directly attack a fire due to intense heat inside of the structure, it can be indirectly attacked outside through a window or
Adequate rock dusting should have been performed to localize any explosion. Dusty conditions in the mine made the mine vulnerable to an explosion, which proved to be true. Scanlan followed protocol in inspecting the mine, keeping detailed record of his findings and reporting to the proper authorities, but there were other things that he could have done to perhaps influence a very different outcome. The following are a few things that
Lightning Field “Lightning field by the American sculptor Walter De Maria, is a work of Land Art situated in a remote area of the high desert of western New Mexico.” (Diaart) Being a sight specific art gives it a lot of potential to use in almost any category. It’s a very strong piece of art but at the same time it can be elegant and calming. “It is comprised of 400 polished stainless steel poles installed in a grid array measuring one mile by one kilometer. The poles -- two inches in diameter and averaging 20 feet and 7½ inches in height -- are spaced 220 feet apart and have solid pointed tips that define a horizontal plane.” (Diaart) This magnificent art is located on a ‘flat plain in the high desert of New Mexico, at an elevation of
An intermediate known as refined iron, refined metal, and refined iron. 5. Iron was used to fuse with carbon to make steel through the foundry. It is also used for the steam ship
The Air Quality Monitor seperates different gasses in smokestacks and determins the amount of gases present so as to meet the smokestack emission requirements. NASA has also influenced our transportaion. A few of the benefits accosiated with these are: Aids to schoolbus design, better brakes, studless winter tires and improved aircraft engines. The school bus;s chassis was redone with NASA technology., making the vehicle safer in the event of an accident. Brakes have been improved with high temperature composite space material that helps improve the lining and strength.
This was the first roller coaster to use a tubular steel track. Unlike conventional wooden rails, tubular steel can be bent in any direction, which allows designers to incorporate loops, corkscrews, and many other manoeuvres into their designs. Most modern roller coasters are made of steel, although wooden roller coasters are still being built. (Wikipedia 2 June 2011) The key physics concepts underpinning the workings of a roller coaster include gravitational energy, kinetic energy, the conservation of energy, centripetal acceleration, and vertical circular motion. Friction also has an important role to play in the construction of a rollercoaster.
