**Unformatted text preview: **ENGR-301 Assignment 3 Assignments must be submitted ONLINE on the course website (using Moodle) Due 23:59 Thursday (28-May-2015) Check the best answer (closest to the exact answer such that the absolute value |answer given – exact answer| is minimum) for each question. 3-1 Your company intends to purchase a 400 tonne capacity injection moulding machine. A similar machine was purchased eight years ago for $89,500. The price index for heavy duty equipment in the plastics industry was 163.6 eight years ago and is 207.6 now. Estimate the current cost of the machine. ($125,000 $113,000 $108,000 $98,000) 3-2 – 3-3 Nadia, John, Saba and Kumar are working together on a project. These are the data for each: Nadia: 60 hours, overhead rate 75%, personal time 10%, $20/hr John: 80 hours, overhead rate 55%, personal time 12%, $40/hr Saba: 80 hours, overhead rate 75%, personal time 10%, $36/hr Kumar: 40 hours, overhead rate 55%, personal time 12%, $20/hr 3-2 Who has the highest direct labour costs? 3-3 Calculate the total direct labour costs (Nadia John Saba Kumar) ($14,800 $14,000 $15,100 $14,300) 3-4 – 3-6 Weldex Industries begins to manufacture a newly designed, small, spot welding machine. The labour hours required for making the second and third units are 28.6 and 28.2 hours respectively. 3-4 Calculate the labour hours required to manufacture the first unit. (28.8 29.1 29.3 29.5) 3-5 Calculate the labour hours required to manufacture the 50th unit. (29.3 27.9 25.5 23.8) 3-6 If labour costs are $18/hour, calculate the total labour costs to produce the first four machines ($1900 $1950 $2000 $2050) 3-7 – 3-10 A 50-mgpd (million gallons per day) water treatment plant was proposed in 2013 for Ureka. A 60mgpd plant using the same treatment process was built in 2007 in Vancouver for $50,000,000. Given the following additional information and assumptions: • • • • • • Poor site condition in Vancouver required an additional $3,000,000 for foundations, which is not anticipated for Ureka. Assume the power sizing size exponent = 0.67. Assume inflation will persist at an average 4% per annum. Assume the location index for Vancouver is 1.17 and 1.24 for Ureka. A new high-pressure filter process will be added at Ureka at an additional cost of $4,000,000. The construction period for the new plant will include winter construction. The Vancouver plant was not constructed through a winter season. Assume an increase in construction costs for Ureka of 12%. In order to make an order of magnitude estimate of the water treatment plant in Ureka, various multiplication factors need to be calculated. 3-7 Calculate the multiplication factor based on the different capacities (0.80 0.90 1.00 1.10) 3-8 Calculate the multiplication factor based on effect of inflation (1.37 1.22 1.42 1.27) 3-9 Calculate the multiplication factor based on the different location indexes (1.07 1.03 0.99 0.95) 3-10 Calculate the order of magnitude estimate of the water treatment in Ureka (35M 50M 65M 85M) ...

## Course Description

ENGR 301 Engineering Communications and Societal Integration (3+0) 3 credits; course is for credit only. ENGR 301 is designated as a service learning course; completion of service learning activity and associated forms are required.

Researching and applying science and technology in societal context; integrating and synthesizing knowledge; communicating information and knowledge via oral, written, and visual presentation.

Prerequisites: ENG 102 and PHYS 181 with a "C" or better; CH 201 or 202; CH 203; junior or senior standing

Satisfies: Core Capstone; CO9 (Science, Technology, & Society); CO13 (Integration & Synthesis); ABET Criteria a, b, d, f, g, h, i, and j.

## Student Learning Objectives

Core Objective 9 (Science, Technology, & Society): Students will be able to connect science and technology to real-world problems by explaining how science relates to problems of societal concern; be able to distinguish between sound and unsound interpretations of scientific information; employ cogent reasoning methods in their own examinations of problems and issues; and understand the applications of science and technology in societal context.

- Students will be able to apply knowledge of mathematics, science, and engineering. [integrates CO2; CO3]
- Students will explain how science relates to a problem of societal concern.

- Students will be able to design and conduct experiments as well as to interpret data. [integrates CO2; CO3]
- Students will distinguish between sound and unsound interpretations of scientific information.

- Students will have a knowledge of contemporary issues. [integrates CO11]
- Students will identify the societal impacts of contemporary issues (such as sustainability, energy problems, water quality, and information science).

- Students will have the broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and societal context. [integrates CO11]
- Students will employ cogent reasoning methods in their own examinations of problems and issues.
- Students will describe how scientific and technological developments affect society and the environment.
- Students will integrate, synthesize, and apply knowledge of the relationship between science and technology and societal issues in both focused and broad interdisciplinary contexts.

Core Objective 13 (Integration & Synthesis): Students will be able to integrate and synthesize Core knowledge, enabling them to analyze open-ended problems or complex issues.

5. Students will be able to function in a multi-disciplinary team. [integrates CO1]

6. Students will have an understanding of professional and ethical responsibility. [integrates CO12]

- Students will identify and analyze the scientific debates and ethical concerns.
- Students will identify the multiple ethical interests at stake in a real-world situation or practice.
- Students will articulate what makes a particular course of action ethically defensible.
- Students will assess their own ethical values and the social context of problems.
- Students will identify ethical concerns in research including academic integrity, use and citation of sources, the objective presentation of data, and the treatment of human subjects.
- Students will demonstrate knowledge of ethical values in non-classroom activities: service learning.
- Students will integrate, synthesize, and apply knowledge of ethical dilemmas and resolutions in academic settings, including focused and interdisciplinary research.
