Engineering Disaster of WTC Tower 7 on 9/11

Name Instructor Task Date Engineering Disaster of WTC Tower 7 on 9/11 A Description of the Engineering Project Certain vulnerabilities in the design of WTC (World Trade Center) likely contributed to the collapse of Tower 7, as well as the two main towers. While the building was exceptionally strong, it had a number of inherent flaws. The original building was a forty-seven storey building with a red granite frontage. The building was 190 meters (610 feet) tall, having a trapezoidal base forty-three meters (140 feet) wide, and 100 meters (330 feet) long (Gilsang and Willa 42). It was constructed above a substation that had a caisson foundation that had been designed to support the weight of a...

MEMs sensors and actuators

Name Professor Name Course Date MEMs Sensors and Actuators Micro-electro-mechanical Systems (MEMS) is a technology, which uses micro-fabrication techniques to make miniaturized mechanical and electro-mechanical devices and structures. MEMS devices satisfy the following criteria: they have a feature size of between one micron and hundreds of micrometer; they have some electrical functionality in their operation; they have some mechanical functionality and have a system-like functionality. These devices can vary from simple structures to complex electromechanical systems. The term MEMS is common in the US whereas the term they use in Europe is Micro Technology System in Europe and Micromachining...

Can engineers be taught creativity?

Can Engineers be Taught Creativity? Can Engineers be Taught Creativity? Introduction Human mind wields tremendous power in changing the very course of history. In this regards, creative thinking and creativity possess tremendous potential to help humans achieving that. For engineers, creativity is the key to unraveling the very solutions of complex and complicated issues as part of designing and innovation.

This paper will look at different aspects of creativity and its importance in the lives of engineers....

Power Systems of Electrical Engineering

Student’s Name Instructor’s Name Course Name Date of SubmissionOptical Interconnects Introduction Optical interfaces refer to arrays of optoelectronic devices that is of the order of 1000 optical channels. Each of these channels run at a speed of approximately 1 Gigabit per second. This means that they offer an overall capacity of the same speed to any single integrated circuit. There are still unresolved issues in manufacturing processes, architectural design, packaging, and simulation. However, due to advanced technology, it is possible to understand its use in all commercial systems within a short period. One of its use is chip-to-chip communication (Mutig). The Use optical methods in...

Plastic molding ” plastic chair “

Plastic Chair Manufacturing via Injection Molding Plastic Chair Manufacturing via Injection Molding Introduction The concept of chair making dates back to Egyptian era where chairs have been symbolized as a mean of power, status, and control. Moreover, the concept of throne has also originated from the very same aspect. In the modernized world, chairs have become commodities and become an essential part of almost every household. For coping up with this demand, chairs have become quite common in different varieties of materials. Among them, plastic chairs become most popular because of their low cost, lighter weight, recyclability options, and ease of transportation. With the...

Woodworking/metalworking

Woodworking/Metalworking Student’s Name Institutional Affiliation Woodworking/Metalworking Introduction An integrated manufacturing system consists of a manual and automated production line. The manufacturing process occurs in phases ranging from the assembling and storage of materials to the production of the final product. However, good manufacturing systems should be efficient in the delivery of the final product as well as providing efficacy production lines. The production line is a series of workstations that allows the passage of products from one series to another with each workstation adding value to the product (Groover, 2007). The paper aims at exploring the manufacturing process...

Gallium Nitride (GaN) based semiconductor to produce blue light

Name Instructor Course Date Producing Blue Light from GaN LEDs Introduction: This state of the art report will focus on light emitting diodes LEDs made from Gallium Nitride (GaN) based semiconductors to produce blue light. The light ought to be of 475 nm in wavelength for high performance and low-cost energy necessary for energy saving light bulbs. The problem this design seeks to address is the operational cost of lighting, longevity and durability compared to the tungsten incandescent lamp. The scope of the research behind this report will focus on how LEDs work by using Gallium Nitride based semiconductors to emit energy at wavelengths of 475 nm, which is the basic characteristic of blue light,...

how did i choose my major

Tutor Name Subject Date The reason I chose mechanical engineering as my major As a student, the choice of subjects is often informed by personal goals, ambitions and above all, passion. Choosing to major in a given area of specialization needs a serious deliberation and a great deal of an afterthought. As a student, the basis for choosing a major in mechanical engineering was solely based on my good performance in mathematics and science. As if this was nothing to go by, I had curiosity in design and evaluation of systems used in end product production. “ In some regions, engineers have combined multiple sources of power to fuel growing needs” (page 5) .The compelling desire to use...

failure mechanism of impeller of centrifugal pumps

Failure Mechanisms of Centrifugal Pump Impeller Abstract Pumps are the prime movers in different process industries. Being a backbone of successful plant operations, centrifugal pumps are subjected to some potential risks that can result in impeller failures. Centrifugal pump impellers are highly susceptible to different failures. The core failures discussed includes cavitation, erosion, and corrosion. Each of these major classes of failures is further sub-divided based on their probable causes along with the degree of severity. Cavitation arises by reduction of suction pressure, low inlet fluid flowrate and Net Positive Suction Head Available (NPSHA) less than Net Positive Suction Head...
