Pollution from automobile emissions has become over the past few decades an issue of great concern. With a growing number of motor vehicles on our roads great concern has been attributed to the effects of these emissions to our health and to the environment. Several of the gases emitted, which when present in certain concentrations in our atmospher
The process of rehabbing a building takes many steps. When you are making these changes you must tear down existing walls, change all electrical installation, and redo plumbing and many other jobs. The goal of a rehab is to make the building look interesting and then you can sell the units easily.
The first step in remodeling a building
In the electronics world everybody is using electromagnetism in some way. All signals are electromagnetic, so in the electrical engineering environment electromagnetism is a leading topic of concern. One of our out of class assignments was to interview a practicing engineer. I was assigned to interview Mr. Gary J Trennison. Mr. Trennison is head en
Many structural components are subjected to cyclic loading. In these components, fatigue damage is the prime factor in affecting structural integrity and service life. Fatigue damage is typically divided into three stages: crack initiation, crack propagation and final failure. These three stages are important in determining the fatigue life of stru
Hazus is a FEMA sponsored program developed to help perform a damage analysis due to a disaster. Currently, Hazus is only capable of estimating losses due to earthquakes. FEMA is in the works of developing future software that will make Hazus capable of analyzing floods, tornadoes, and hurricanes.
Hazus uses probability to make loss est
A screw used as a threaded fastener consists of a shaft, which may be cylindrical or conical, and a head. The shaft has a helical ridge or thread formed on it. The thread is essentially an inclined plane wrapped around a shaft. The thread mates with a complementary helix in the material. The material may be manufactured with the mating helix (tappe
Your basic two-slice toaster
You can purchase a toaster at any discount store for less than $20 (U.S.). The particular model shown on the right allows you to set the darkness of the toast it produces and also has a defrost mode.
The basic idea behind any toaster is simple. A toaster uses infrared radiation to heat
In response to the terrorist attacks of 11 September 2001 and the perceived risks to ships and the danger of ships being used for terrorist purposes, the International Maritime Organization (IMO) began extensive work towards modifying the Convention for the Safety of Life at Sea (SOLAS) 1974 (as amended) and creating
Internal combustion engine is an engine, in which the fuel is burned (that is, united with oxygen) within the engine itself. If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gases. The expanding gases are converted into mechanic
LA LOGISTIQUE ASSOCIÉE AU TRANSPORT DES MATIÈRES DANGEREUSES: Le Cammionnage
Le transport est un secteur important de l’économie canadienne. La mode transport routier est le plus utilisé pour le transport de marchandise, le transport ferrovier et maritime viennent par la suite et enfin le transport aérien pour acheminer les marchandises aux
Depuis quelques années, lOrdre des Ingénieurs du Québec a accompli un progrès significatif en apportant une emphase croissante sur le professionnalisme et la responsabilité professionnelle dans la formation des nouveaux ingénieurs. Certains craignaient que la responsabilité professionnelle ait été sous-estimée dans la pratique de la profession. L
Starting in the late 1700’s, European engineers began tinkering with motor powered vehicles. Steam, combustion, and electrical motors had all been attempted by the mid 1800’s. By the 1900’s, it was uncertain which type of engine would power the automobile. At first, the electric car was the most popular, but at the time a battery did not exist that
In chapter 5 of The Biotech Century, Rifkin takes a stand on the nature side of the debate. He backs his positon up by citing several examples of genetic research that have reported on finding links among genes and psychological diseases. I chiefly believe that the nature plays more significant role in shaping human life in general than the nurture
