Chapter 4.12, Problem 6P
Draw an objective tree for the following: If you drive in the state of Florida, you may notice some traffic congestion when crews trim trees on the state roads and freeways. Assume that the Florida Department of Transportation is the client. Usually, branches 6 inches or less in diameter are trimmed. The allowable horizontal distance from the edge of the road to the branches is 6 feet. The material removed from the trees must be collected and removed from the roadside. To reduce the cost of trimming, a maximum of only two workers can be assigned for each machine. The overall cost, which includes equipment and labor must be reduced by at least 25% from present cost. The state claims that the demand for your machines will follow the price reduction—that is, if you are able to reduce the cost by 40%, the demand will increase by 40%. Allowable working hours depend on the daylight and weather conditions.

In February of 2010, architects and consulting engineers all over Bastonia, were seeking out any available defense attorneys with experience in criminal law. These activities were brought on by subpoenas issued by the Attorney General of Bastonia Jose Paleri, who was looking into charges of bribes and kickbacks given to elected statesmen by engineers working in the construction industry. The subpoenas required the engineers to submit the records of their firms to the office of Attorney General of Bastonia. Leonardo Marsiano, who was a partner of Marsiano and Associates Inc.., was one of these engineers. The susequent events were highly published by Baskonia press and finally led to the resignation anddisgrace of Santana Spirola when he was the Minister of Public Works in Baskonia.Leonardo Marsiano was an engineer trained at a prestigious university. Eventhough his firm was doing well, in case of big public-work contracts, they werecontinuously losing to other firms. In Baskonia,…

- After creating a decision matrix for two types of materials used to design a safety belt, an engineer assigns a weight of 4 to nylon for thickness and a weight of 5 to polyester for thickness. The engineer also assigns a weight of 4 to nylon for strength and a weight of 3 to polyester for strength. Polyester is more expensive than nylon.

- Tony’s Barbershop is run, owned, and operated by Anthony Jones, who has been cutting hairfor more than 20 years. Anthony does not take appointments, so the arrival pattern of customers is essentially random. Traditionally, the arrival rate had been about one customer every50 minutes. Two months ago, the local paper ran an article about Anthony that improved business substantially. Currently, the arrival rate is closer to one customer every 35 minutes. Haircutsrequire an average of 25 minutes, but the times vary considerably depending on customerneeds. A trim might require as little as 5 minutes, but a shampoo and styling could take as longas an hour or more. For this reason, the exponential distribution seems to provide a reasonablygood fit of the service time distribution.Anthony’s customers have always been patient, but ever since business picked up, somehave complained that the wait is too long. Anthony is considering taking his cousin Marvin intothe business to improve customer…arrow_forwardYour capstone design team is prototyping (e.g. you are building a model to test not a final product) a "fire identification drone.

Provided in the last part are the guides and examples: The process for large-scale manufacture of paper has been largely unchanged for the last 125 years. The pulp and paper industry today is highly capital intensive, and there is an ongoing drive towards process integration, thereby increasing the efficiency of utilization of available process resources. This paper deals with the Kraft process (see Fig. 1) though the general principles described can be extended to other pulping processes. As shown in Figure 1, five water sinks and four water sources are considered for in-plant water reuse/ recycle. Prior to water reuse/ recycle, the network requires a freshwater flow rate of 36,400 tonne/day and generates 37,186 tonne/day of wastewater (sum of the individual sink and source flow rates in Table 1).

- 9. A defense department assigned its highest priority to develop an advanced aircraft using materials not previously used and untested technologies. A firm fixed-price contract was awarded to a qualified vendor. Controls were in place at all levels, and progress reports—noting challenges—were sent to top officials. Top officials reported that progress was excellent, but the project failed due to enormous expenditures with no aircraft developed. Which risks were not adequately considered? I. Because the requirements were not specific, the use of a firm fixed-price contract made the project risky. II. The personnel at many levels sent false reports forward on cost incurred and progress made. III. The contractor lacked adequate technical skills to deal with technology that was still evolving. IV. Top procurement officials did not act on “red flags” due to a “can do” mentality on a high priority of the program.

For an object of uniform composition, its centroid is also its center of mass. Often the centroid of a complex composite body is found by, first, cutting the body into regular shaped segments, and then by calculating the weighted average of the segments' centroids.An object is made from a uniform piece of sheet metal. The object has dimensions of a = 1.45 ft, where a is the diameter of the semi-circle, b = 3.24 ft, and c = 2.10 ft. A hole with diameter d = 0.500 ft is centered at (1.13, 0.725).
