The figure shows a structure composed of a beam and a system of springs that supports a box weighing 20 kips. Use the spring stiffness and mechanical properties of the beam given in the figure. Using the vertical displacement of the box as the degree of freedom and the equivalent spring method, determine the equation of motion for free vibrations. Also calculate the frequency and natural period. You can neglect the self-weight of the beam.

The mean weight of five complete computer stations is 167.2 pounds. The weights of four of the computer stations are 158.4 pounds, 162.8 pounds, 165.0 pounds, and 178.2 pounds respectively. What is the weight of the fifth computer station?
11 Sunco Oil has refineries in Los Angeles and Chicago.The Los Angeles refinery can refine up to 2 million barrelsof oil per year, and the Chicago refinery up to 3 million.Once refined, oil is shipped to two distribution points:Houston and New York City. Sunco estimates that eachdistribution point can sell up to 5 million barrels per year.Because of differences in shipping and refining costs, theprofit earned (in dollars) per million barrels of oil shippeddepends on where the oil was refined and on the point ofdistribution (see Table 51). Sunco is considering expandingthe capacity of each refinery. Each million barrels of annualrefining capacity that is added will cost $120,000 for the LosAngeles refinery and $150,000 for the Chicago refinery. Uselinear programming to determine how Sunco can maximizeits profits less expansion costs over a ten-year period.

Nondestructive evaluation: Nondestructive evaluation (NDE) describes methodsthat quantitatively characterize materials, tissues, and structures by noninvasivemeans such as X-ray computed tomography, ultrasonics, and acoustic emission.Recently, NDE was used to detect defects in steel castings. (JOM, May 2005.)Assume that the probability that NDE detects a “hit” (i.e., predicts a defect in a steelcasting) when, in fact, a defect exists is .97. (This is often called the probability ofdetection.) Also assume that the probability that NDE detects a “hit” when, in fact,no defect exists is .005. (This is called the probability of a false call.) Past experiencehas shown that a defect occurs once in every 100 steel castings. If NDE detects a“hit” for a particular steel casting, what is the probability that an actual defectexists? Step by Step Full procedure required.
