classes of materials show differences in creep behaviour. • Awareness of creep as a design consideration. 2. THEORY 2.1 Introduction Structural materials are often placed in service under a certain applied load at elevated temperatures (eg. wind turbines). Over time, the material elongates as a result of the strain accumulated and deforms. Such time-dependent deformation is dubbed as creep. Creep deformation can happen due to long-term exposure to high levels of stress, albeit still below the…

INTRODUCTION Worldwide, air pollution is a growing threat to human health and the natural environment. One of the major effects of air pollution is acid rain and it is caused by sulfur dioxide (SO2) and nitrogen oxides (NOx) gases. The combustion of high sulphur content fossil fuels can release harmful toxic gases into the air and therefore pose serious environmental problems. Coal, oil and natural gas are major energy resources available in environment where as fuel combustion processes and…

Introduction By the year 2010, there were only one billion cars globally. Transportation for humans began with walking. After the domestication of animals donkeys, camels, and horses were used for transportation. Animals and the invention of the wheel led to carriages which then led to trains. Since then, transportation has evolved with new technology which has created cars, ships, and flight. Through years of development, transportation has greatly affected life. As the world continues to…

future. Other renewable technology can be analyzed for the same system and cost comparison is one of the best work that can be done in view of market potential. The impact of DFIG i.e. doubly fed induction generator and different controls of wind turbines can be studied as integration of these combinations can make the system more…

Survival Strengths By: Abby J, Thomas P, Cierra D, and Devon F Imagine, you’re on a plane and the plane’s turbines explode. The plane suddenly crashes into the water. You somehow make it out alive and wake up on a deserted island. What strength would you need? Physical, Mental, Emotional? You may need them all, but what’s most crucial? Mental-why you might ask, let us explain. We believe that mental strength is the most important in survival situations. Let us revisit the previous…

Nuclear energy, or power, is the process by which nuclear processes beneath the earth 's surface are utilized in such a way that they safely produce heat and electricity at a relatively cheap cost. Nuclear energy has made tremendous strides in the recent years but has faced opposition from innumerable sources which have effectively stunted the growth of this form of energy. Events such as the Chernobyl disaster have given nuclear power a bad reputation but have also forced a pursuit of safer…

are fuels that are extracted from the earth, this means that they are a limited resource. This creates the need for renewable energy. Renewable energy comes from sources such harnessing power from the sun in solar panels, or using wind with wind turbines. Combustion is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant that produces…

create energy. The plant uses these process in water to ease the process, in where the isotope splits it releases neutrons and heat. This is a process that continues releasing even more neurons and heat. After this the heat is then used to spin a turbine to create power to then create energy. By using nuclear fission energy it could last longer and use less of the governments money. Although many energy sources do carry significant human health and environmental risks. Out of all energy uses…

function based, citizens live in a specific areas, and commercial sector is where commerce, shopping, postal services, food services occur. There are two power sectors one that is water based and one that is land based. Hydro powered systems and wind turbine technologies are located close to the coast. The industrial sector is concentrated in a single area as well. The services sector offers the government services, such as emergency services, schools, town halls, and churches exist here.…

Garage Workshop I've done it countless times. I walk up the driveway of my dad’s generic suburban ranch house and open the fading, white garage door. The lights on either side of the door mirror each other and are always shining. Once the door finishes its loud opening sequence, I stare at the rusty decklid and tail lights of my Mustang. Off to the right of the car is a wall filled with shelves. The shelves are filled with miscellaneous items such as, christmas decorations, basketballs, and…
