Which of the following stakeholders is least important to the design process: a) The crib company. b) Parents who purchase the crib. 0) Government agencies that regulate the product safety standards. d) Retailers that will stock the crib in their stores. e) Loggers that harvest trees used in the manufacturing process.

The following passage contains at least 10 writing errors/problems. Identify five of the errors by circling each error, and labelling the errors 1 through 5. (5/20) Detailed Design #1 Based on a results from the evaluation of objectives and the consultation with the client (please see decision making processes in appendix B for pair-wise comparisons and morphological charts) we decide that the best possible solution for Tyndale is to replace a number of static shelves in the library’s basement. The design had called for replacing 2 quadrants in the library basement with compact shelves (refer to appendix A for library layout). Contacted many Canadian based storage companies, and the company that gave us the most useful feedbacks are SpaceSaver a branch from Montel (an internationally known shelving organization (MTM)) based in Aurora who has actually worked with Tyndale in the past. According to the datum, each of the regular double—sided static shelves (Appendix A, figure 4) in the library’s basement currently stores approximately 2100 books on average. We estimated the average weight of a book to be 2.5 N, thereby making the total amount of books in each double- sided shelf approximately 23350 N. Since Tyndale desperately desires to expand its collection by 5200 books per year for the next three years (a total of 15600 books approximately, occupying about 2016 of the library space), it will requireapproximately 8 regular static double- sided shelves to allow for the minimum expansion required. However, it’s likely that the library may expand its collection by more then the minimum required amount. Currently their is no free space in the library to insert any static shelves without compromising the area of the workspace or book accessibility, which are both implausible. The installation of a compact shelves typically reduced the space needed by 50% [4], therefore, the best solution to the problem would be to replace some existing static shelves with compact shelving units. This solution will liberate Tyndale library from its space constraints with a new and improved look that preserves the historic character of the workspace without infringing on existing storage areas.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
