MEE 3090 HW Problem 13-9 To avoid the problem of interference in a pair of spur gears using a 25° pressure angle, specify the minimum number of teeth allowed on the pinion for each of the following gear ratios. (a) 2 to 1 (b) 3 to 1 (c) 4 to 1 (d) 5 to 1 Problem 13-10 For a spur gearset with ϕ = 20°, while avoiding interference, find: (a) The smallest pinion tooth count that will run with itself (b) The smallest pinion tooth count at a ratio mG = 2.5, and the largest gear tooth count possible with this pinion (c) The smallest pinion that will run with a rack Problem 13-17 Shaft a in the figure rotates at 600 rev/min in the direction shown. Find the speed and direction of rotation of shaft d. Problem 13-22 A compound reverted gear train is to be designed as a speed increaser to provide a total increase of speed of exactly 30 to 1. With a 20° pressure angle, specify appropriate numbers of teeth to minimize the gearbox size while avoiding the interference problem in the teeth. Assume all gears will have the same diametral pitch. Problem 13-24 A gearbox is to be designed with a compound reverted gear train that transmits 25 horsepower with an input speed of 2500 rev/min. The output should deliver the power at a rotational speed in the range of 280 to 300 rev/min. Spur gears with 20° pressure angle are to be used. Determine suitable numbers of teeth for each gear, to minimize the gearbox size while providing an output speed within the specified range. Be sure to avoid an interference problem in the teeth. Problem 13=29 A compound reverted gear train is to be designed to provide the appropriate ratio between the minute hand and the hour hand of a clock. The hour hand is attached to the shaft of gear 5, such that the rotational speed of the hour hand will equal the rotational speed of gear 5. The shaft of gear 2 passes through the center of the hollow shaft of gear 5, and has the minute hand attached to it. Use spur gears with a 20° pressure angle. Specify appropriate numbers of teeth, while minimizing the gearbox size and avoiding the interference problem in the teeth.

The assignment is to write no more than 10 pages report of a real-life project, please read the below carefully. The project in the Engineering Project Management course is an application of the material covered within that course. The student should select a real-life project for which data is available. The project can be from his side or his partner’s side. Students are requested to work in groups. Maximum a three-student size group. After selecting the appropriate project, the team should do the following: 1. Write a briefing statement about the project: which is the current project with the surrounding circumstances. 2. Develop a full WBS for the project 3. Develop a budget and show the budget using the appropriate way you prefer (a button-up approach has to be used) 4. Schedule the project using networking 5. Crash or expedite the project 6. Allocate resources 7. Discussion and Recommendation- after looking at your project, discuss your findings and conclude Note: in your attempt to build the WBS, or even the budget elements, provide a brief discussion of how you came up with your numbers, and show some demonstrations of your work by discussing some elements for which the WBS, or the budget have been developed Make sure to write the project report in a unique way with zero plagiarism and without Artificial Inelegance (AI) assistance.

Fayez Fikry ARCH 302: Introduction to Architectural Engineering Original content by: Dr. Sahera Bleibleh 1 OBJECTIVES: 1. Introduce students to the Architectural Engineering professions, roles and responsibilities [1,2]. 2. Discuss an engineering design process through technical and contextual analyses [4]. 3. Explain building design and systems integrations [1,2]. 4. Communicate design solutions effectively through oral and graphical materials, techniques and modern engineering tools [5].

Physical Characteristics of the Site The arrangement of buildings and spaces on a site will influence the building ‘footprint’, private open space, semi-public open space, setbacks for amenity, street appearance, existing shade trees, access and parking, services and facilities. https://www.freelancer.com/u/tndstudio007/portfolio/Site-Analysis-6639818?w=f&ngsw-bypass= ARCH 302: Introduction to Architectural Engineering Original content by: Dr. Sahera Bleibleh 9 Step 2: Understand the Site • Understanding the site is critical in refining and shaping the eventual development. A site analysis process will help this understanding. • It enables both on-site and off-site constraints and opportunities to be identified. • A Site Analysis Plan will vary depending on the nature of the development, the size of the site and the prevailing context. • The site analysis establishes the development context, identifying and explaining graphically: 1.The key influences on the design; and 2.How the proposed development will relate to the immediate surroundings ARCH 302: Introduction to Architectural Engineering 10 Original content by: Dr. Sahera Bleibleh 9/4/2023 How the proposed development will relate to the immediate surroundings? Reference to street character is also important. Street character can provide important clues for successful integration and may influence site layout, landscape, alignment of the design of the proposed development in relation to the streetscape. https://www.re-thinkingthefuture.com/fresh-perspectives/a564-what-is-a-streetscape-and-why-architects-should-care/ https://www.firstinarchitecture.co.uk/architecture-site-analysis-guide-2/ ARCH 302: Introduction to Architectural Engineering Original content by: Dr. Sahera Bleibleh 11 Step 3: Prepare a Site Analysis Plan • A Site Analysis Plan is a critical tool in the design and assessment of development applications. • A Site Analysis Plan must be to scale and should identify development opportunities and constraints. • It should be used to influence the design of a development, to minimize negative impacts and compliment neighborhood character. https://www.pinterest.com/pin/76772368634856002/ ARCH 302: Introduction to Architectural Engineering 12 Original content by: Dr. Sahera Bleibleh 9/4/2023 Example of Site Analysis https://www.pinterest.com/pin/363736107388560539/ ARCH 302: Introduction to Architectural Engineering Original content by: Dr. Sahera Bleibleh 13 Example of Solar Study in Site Analysis https://bimbakery.co/product/sun-path-object/ https://www.pinterest.com/pin/166422148705551344/ ARCH 302: Introduction to Architectural Engineering 14 Original content by: Dr. Sahera Bleibleh 9/4/2023 Site analysis with Vehicular study https://www.firstinarchitecture.co.uk/architecture-site-analysis-guide-2/ https://www.archdaily.com/785806/student-housing-cf-moller/5715c546e58eceac8b00013a-student-housing-cf-moller-flows-diagram ARCH 302: Introduction to Architectural Engineering Original content by: Dr. Sahera Bleibleh 15 Site Analysis studying the pro and cons of existing facilities ARCH 302: Introduction to Architectural Engineering 16 Original content by: Dr. Sahera Bleibleh 9/4/2023 Site Analysis Plan A typical Site Analysis Plan might look like the plan on the right.

ARCH 302: Introduction to Architectural Engineering 18 Original content by: Dr. Sahera Bleibleh 9/4/2023 Step 4: Site Analysis Plan and Statement A Site Analysis Statement prepared by the applicant explaining how the design has responded to the Site Analysis Plan will greatly assist the design and assessment processes, resulting in a significant improvement in the quality of the development and should accompany the Site Analysis Plan. During the site analysis process: 1. Identify issues to consider in the design process; and 2. The design elements applicable to the particular development should be identified following the site analysis process and these elements should guide the design process.
