  • Viscoelastic Behavior of Foamed Polystyrene/Paper Composites
    Session 2793 Viscoelastic Behavior of Foamed Polystyrene/Paper Composites Robert A. McCoy Youngstown State University Introduction This paper outlines a simple lab experiment for high school students or freshman engineering students designed to demonstrate the principle behind why sandwich composites are so stiff as well as light-weight. A sandwich composite consists of a very lightweight core (such as a foamed polymer or honeycomb structure) with sheets of another material (such as paper, plastic, fiberglass, or aluminum) on the top and bottom surfaces. Applications for sandwich composites requiring both high-stiffness and lightweight include aircraft panels, boat hulls, jet skis, snow skis, partitions, and garage doors. In this experiment, the students measure the increase in stiffness when the top and bottom skins of paper are added to a Styrofoam beam to form the sandwich composite. Also this experiment includes a creep test in which the students measure and plot the deflection of the Styrofoam beam versus time to illustrate the viscoelastic behavior of Styrofoam. Materials and Equipment Required 1. A sheet of Styrofoam (foamed polystyrene) approximately 122 cm (4 ft) long, 35.5 cm (14 in) wide, and 1.83 cm (0.72 in) thick. 2. A metal frame with a clamp to hold one end of the Styrofoam beam. 3. Six metal washers, about 3.8 cm (1.5 in) diameter. 4. One jumbo paperclip. 5. One large paper grocery bag. 6. Scissors, cutting knife, and paper glue. 7. A ruler or meter stick. 8. A weighing scale or balance 9. A computer with MS Excel Procedure For each group of students performing this experiment, at least four rectangular bars approximately 2.5 cm (1 in) wide and 35.5 cm (14 in) long were cut from the Styrofoam sheet.

  • Weighing Scale 1 Weighing Scale
    Weighing scale 1 Weighing scale A weighing scale (usually just "scales" in UK and Australian English, "weighing machine" in south Asian English or "scale" in US English) is a measuring instrument for determining the weight or mass of an object. A spring scale measures weight by the distance a spring deflects under its load. A balance compares the torque on the arm due to the sample weight to the torque on the arm due to a standard reference weight using a horizontal lever. Balances are different from scales, in that a balance measures mass (or more specifically gravitational mass), whereas a scale measures weight (or more specifically, either the tension or compression force of constraint provided by the scale). Weighing scales are used in many industrial and commercial applications, and products from feathers to loaded tractor-trailers are sold by weight. Specialized medical scales and bathroom scales are used to measure the body weight of human beings. History Emperor Jahangir (reign 1605 - 1627) weighing The balance scale is such a simple device that its usage likely far his son Shah Jahan on a weighing scale by artist predates the evidence. What has allowed archaeologists to link artifacts Manohar (AD 1615, Mughal dynasty, India). to weighing scales are the stones for determining absolute weight. The balance scale itself was probably used to determine relative weight long before absolute weight.[1] The oldest evidence for the existence of weighing scales dates to c. 2400-1800 B.C.E. in the Indus River valley (modern-day Pakistan). Uniform, polished stone cubes discovered in early settlements were probably used as weight-setting stones in balance scales.

  • Chapter 3: Basic of Applied Mechanical Measurement
    CHAPTER 3: BASIC OF APPLIED MECHANICAL MEASUREMENT 3.1. Introduction Basic quantities for measurement in mechanical field are measurement for length, mass, time, temperature and angle. These quantities can be obtained using certain measurement devices. Several measurement devices can measure some of the quantities, while the remains need to use specific measurement devices. Classification of mechanical measurement and its measurement devices that will be discussed are as follows: No Mechanical quantities Measurement devices 1 Linear dimension • ruler • caliper • micrometer caliper • vernier caliper • dial gauge 2 Mass • mechanical balance • spring balance 3 Force • spring coil • proving coil • strain gauge • load cell 4 Torque • brake • dynamometer • strain gauge • transducer Temperature, pressure and other quantities will be discussed later. 3.2. Linear Dimension Measurement 3.2.1 Micrometer A micrometer is a widely used device in mechanical engineering for precisely measuring thickness of blocks, outer and inner diameters of shafts and depths of slots. Appearing frequently in metrology, the study of measurement, micrometers have several advantages over other types of measuring instruments like the Vernier caliper - they are easy to use and their readouts are consistent. There are three types of micrometers based on their application: • External micrometer • Internal micrometer • Depth micrometer 41 An external micrometer is typically used to measure wires, spheres, shafts and blocks. An internal micrometer is used to measure the opening of holes, and a depth micrometer typically measures depths of slots and steps. The precision of a micrometer is achieved by a using a fine pitch screw mechanism. Figure 1: External, internal, and depth micrometers 3.2.1.1 Reading an Inch-system Micrometer.

  • UNIT 1 ANTHROPOMETRY Introduction Practical Is Basically an Application of the Theoretical Knowledge
    UNIT 1 ANTHROPOMETRY Introduction Practical is basically an application of the theoretical knowledge. It occupies an irreplaceable envious position for understanding the intricacies of human growth and development. Human growth and development is continuously on move to understand our past, present and future intrinsically. It has opened the doors for applied research in diverse fields and continues to be committed to understand every aspect of man more minutely, because of its strength to absorb new techniques in its framework. It also communicates immense information about the shape, size, body composition and physique of an individual. It facilitates in appreciating the variations in various body measurements among different individuals and different populations. Not only this but practical in human growth and development play a pivotal role in assessing physical growth of children, health status and nutritional status of adolescents and adults is also assessed with the help of these measurements. Disease and determination of certain physiological functions like vital capacity, basal metabolic rate and work capacity rely on anthropometry and its valuable contribution for racial comparisons or variations in body. Anthropometry data is an asset for designing proper equipment for use in industry and defence purposes, spaceships, garments, etc and also to provide norms of the physique of any population and trends of changes in morphological traits. Various body measurements involving segmental lengths, breadths, circumferences and skinfolds are used for research and designing the instruments and apparatus used by us. Anthropometry constitutes two components a) Osteometry b) Somatometry Osteometry is the measurement of skeleton. Further osteometry encompasses measurement of skull along with measurement of teeth as well as measurement of post cranial skeleton.
