  • Although Iraq remains hostile to the United States, Baghdad has repeatedly compromised, and at times caved, in response to U.S. pressure and threats. An analysis of attempts to coerce Iraq since Desert Storm reveals that military strikes and other forms of pressure that threatened Saddam Husayn’s relationship with his power base

  • In the early years of oil drilling and production, wells were primarily drilled on land to moder- ate depths and with relatively minor horizontal offsets, and an empirical understanding of the impact of geological forces and Earth material properties on required drilling practice was de- veloped by region. Successful practices were defined by trial and (sometimes costly and spectacular) error.

  • Practically every industrial process requires objects to be moved, manipulated or be subjected to some form of force. This is generally accomplished by means of electrical equipment (such as motors or solenoids), or via devices driven by air (pneumatics) or liquids (hydraulics).

  • Satellite altimetry was developed in the 1960s soon after the flight of artificial satellites became a reality. From the vantage point in space, a radar altimeter is able to measure the shape of the sea surface globally and frequently. Such measurements have a wide range of applications to oceanography, geodesy, and geophysics. The results are often revolutionary. For example, in oceanography; it takes a ship weeks or months to cross the ocean making measurements while the ocean is constantly changing its circulation, temperature, and salinity.

  • Find the shear and normal stresses on plane AA cutting through at 30°. Solution: Make cut “AA” so that it just hits the bottom right corner of the element. This gives the freebody shown at right. Now sum forces normal and tangential to side AA. Denote side length AA as “L.”

  • Pressure Plates, shock absorbing The Shock Absorbing Pressure Plate is designed to counter the 3 main problems encountered in pressing work: • extreme impact loads • high noise levels • risk of lower quality parts. The Shock Absorbing Pressure Plate contains specially developed damping which reduces the undesirable shock loads which result in high costs for press maintenance, excessive noise and lower quality parts.

  • Helicopter aerodynamics is the branch of physics dealing with the forces and pressures exerted by air in motion. The atmosphere, the mass of air, which completely envelops the earth, is composed of varying and nonvarying constituents. The nonvarying constituents include oxygen (21%) and nitrogen (78%). The varying constituents include CO2, argon, hydrogen, helium, neon, krypton, and water vapor, which will vary from negligible amounts to approximately 4% by volume (100% relative humidity). Air is a fluid and is affected by changes in temperature, pressure, and humidity....

  • We present an array of force spectroscopy experiments that aim to identify the role of solvent hydrogen bonds in protein folding and chemical reactions at the single-molecule level. In our experiments we control the strength of hydrogen bonds in the solvent environment by substituting water (H2O) with deuterium oxide (D2O). Using a combination of force protocols, we demonstrate that protein unfolding, protein collapse, protein folding and a chemical reaction are affected in different ways by substituting H2O with D2O.

  • Many students wait until the last minute to write papers, hoping that the pressure of deadlines will force out well-organized facts and deep analysis directly onto the page. If you can write good papers at the last minute and feel good about doing so, then read no further. But if you find yourself feeling uneasy with your writing expertise, if your graduation paper topic puts you out on a limb, or if the papers turn out to be not as good as they might be, then consider a change of habit.

  • In this chapter we will consider an important class of problems in which the fluid is either at rest or moving in such a manner that there is no relative motion between adjacent particles. In both instances there will be no shearing stresses in the fluid, and the only forces that develop on the surfaces of the particles will be due to the pressure. Thus, our principal concern is to investigate pressure and its variation throughout a fluid and the effect of pressure on submerged surfaces. The absence of shearing stresses greatly simplifies the analysis and, as we will see,...

  • Pipe stress analysis calculates the stress in a piping system subject to normal operating loads such as pressure, weight, and thermal expansion, and occasional loads such as wind, earthquake, and water hammer. Because all piping systems are connected to equipment such as vessels, tanks, pumps, turbines, and compressors, the piping stress analysis also involves evaluation of the effect of the piping forces and moments to the connecting equipment. As the piping stress is controlled by the arrangement of the supports and restraints, the scope of piping stress includes also pipe supports.

  • General Appearance of the Product Parting Line Flash Good molds have venting around most of, if not the whole length of the parting line. As long as the stack and the vents are designed properly, there should never be flash on the parting line. If flashing does occur despite a properly designed and built mold, there could be a number of other causes: The selected molding machine has not enough clamp force (tonnage) for the projected area of the cavity and the required injection pressure or was not adjusted properly. ...
