CREEP AND MECHANICAL TESTING ROSE SIMON Abstract The experiment consisted of two parts of investigation‚ Mechanical and Creep testing. Under mechanical testing‚ two medium carbon steel (04%) specimens that had been through different heat treatment were tested on tension and for hardness. One had been cold drawn and the other

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

As I woke up this morning‚ President of the United States‚ I felt proud and brave. The day is October 14‚ 1962. One of our U2 spy planes pick up something strange.

My First Plane Ride The 21-hour voyage all begins when you step aboard the Boeing 747. For me this was my first plane ride. My parents and I were departing from LAX and our destination was Myanmar or Burma. I was probably 6 years of age waiting to see my relatives in Burma for the first time. Before we took off I was so excited‚ but when the plane started to take off my excitement turned converted to fear. Fortunately‚ about 2 minutes later the plane lost its slope and the roar of its engines

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

Montessori Philosophy: The Planes of Development Most people’s idea of how children grow and develop is a steady continuous movement along a path from point A ’’ birth‚ to point B ’’ adulthood. Maria Montessori’s philosophy on how humans learn differs in that she believed learning for children and youth occurred as a series of waves or cycles. After years of observation‚ Montessori concluded there are four distinct planes of development that everyone must pass through on their way to

Montessori theory of “ Four Planes of Development ”. According to her there are different types of mentality in the phases of growth which are quite distinct one from another and they correspond with the phases of physical growth. Each of them can be considered as a level or plane of six years and a set of psychological characteristics can be observed in each level and the features of each plane are so different from one to another in a way that the passage from one plane to the next one can be considered
