OF THE IEEE‚ VOL. 70‚ NO. 5‚ MAY 1982 Silicon as a Mechanical Material KURT E. PETERSEN‚ MEMBER‚ IEEE Abstract-Single-crystal silicon is being increasingly employed in a variety of new commercial products not because of its well-established electronic properties‚ but rather because of its excellent mechanical properties. In addition‚ recent trends in the engineering literature indicate a growing interest in the use of silicon as a mechanical material with the ultimate goal of developing a broad

However to me this machine is responsible for sparking an interest in how things work. My love for practical sciences‚ in addition to my innate fascination with technology used for practical and real purposes‚ has enabled me to discern my love for mechanical engineering. As a chubby 11 year old‚ I remember sitting glued to Discovery channel. An episode of the show ‘How it’s made’ featured the process used to create a gumball machine. Awestruck I learnt about the intricate parts that made this miraculous

engineer. I am interested in SIUE’s Mechanical Engineering program. Mechanical Engineering is an exciting career field. In my youth‚ I was constantly designing and building an assortment of contraptions out of LEGO’s and K’NEX pieces. These objects included rollercoasters‚ cars‚ buildings‚ tractors‚ and many other machines. Growing up on a farm‚ I have always been interested in agriculture. There are many reasons why I’m interested in the Mechanical Engineering program at SIUE. This program

Mechanical energy Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Introduction: We use a system consisting of two weights hanging at each end of a thin thread lying over a wheel. A photo gate is placed so that the light is interrupted by the spokes of the wheel. The data are recorded electronically and this makes it possible

Is There a Future for Mechanical Beings? In today’s fast-paced society we ask ourselves a series of questions: Did I let the dog out? What’s for dinner tonight? How am I going to find the time to finish my English essay? I believe these questions can be answered by the developmental studies of machines known as robotics. The machines themselves are called robots. Robots are mechanical beings capable of operating as humans. Throughout my life I have been fascinated by Artificial Life (A.L

Defn. of Digestion: the process whereby a biological entity processes a substance‚ in order to chemically convert the substance into nutrients. It usually involves mechanical manipulation and chemical action. Mechanical Digestion What is it? This type of digestion involves the mixing‚ grinding or crushing of large pieces of food into smaller places. Why does it take place? So that the food we consume is broken down into smaller pieces before we swallow it which in turn makes process of

Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature
