  UBC Engineering students, staff and faculty shall act at all times with courtesy, honesty, and respect to each other and society. In keeping with their duty to the community, the engineering profession, and the public, they commit to creating a welcoming, respectful and ethical environment that values all members. Accordingly, community members shall: 1.

3.

4.

5.

Uphold the academic integrity of the university and of the UBC Engineering degree, submitting work only when it is founded upon honest efforts and personal achievement. Commit themselves to advance their body of knowledge, engage in professional development, and acknowledge the importance of lifelong learning. Conduct themselves with respect and integrity when interacting with all members of our community and society at large, give credit where it is due and accept, as well as give, honest and fair professional comment. Report any hazardous, illegal, or unethical decisions or practices by any member of our community. Extend public knowledge and appreciation of engineering and protect the profession from misrepresentation and misunderstanding.

This code was adapted, with permission, from the APEGBC Code of Ethics, and agreed upon by the Engineering Undergraduate Society Council.

Notes and tips for this practice exam are contained in these shaded boxes. The questions in this document have appeared in past midterm and final exams. They are intended to aid you in your course review.

Your exam will differ in content and question style. Use this as a study aid – do not treat it as a template for your final exam.

Refer to the course learning goals and course materials (online, lecture, and studio) to determine assessable material. A full APSC 100 final exam is 120 marks (see the cover). Standard APSC 100/101 exam format is based on a target of 1 mark per minute. With a 2.5-hour duration for final exams, this provides a generous amount of time to complete the exam (i.e. you should be able to finish with approximately 30 minutes remaining). Tip: this practice exam has 70 marks. To replicate exam conditions, print a copy of this exam, find a quiet place, and set a timer for 70 minutes. Try to complete all questions within that time; if you need additional time, continue up to a maximum of 85 minutes. Do not look at the solutions until you have finished writing.                                                             1 https://ubcengineers.ca/eus/traditions/ironpin/ Page 2 of 11

Part 1 – Multiple Choice [50 questions, 50 marks] 

Answer all 50 questions. Choose the

best

response – a given question may have more than one choice that is correct, but marks will only be given for the best answer. This sample exam does not include multiple choice questions. For multiple choice question style, refer to the practice midterm or the actual midterm from this course. For practice multiple choice questions for study purposes, refer to the screencast self-tests.

 

Part 2 – Short‐Answer Questions [15 questions, 45 marks] 

Answer all 15 questions

in the spaces provided.

The size of the answer boxes should guide you to how detailed your response should be - work outside the boxes will

NOT

be graded.

For full marks, answers need to be clear, concise, and legible.

Each question is worth 3 marks. Questions on your exam will differ in content and style. See the solutions document for additional notes on each question, and in particular for questions marked with “*”.

  1.

List nine key stakeholders in the Site C Clean Energy Project. (For full marks, give a diverse list of stakeholders.) * 2.

You have been asked to give example comments to accompany a grading rubric. The rubric will be used for APSC 100 students to conduct a peer review of the other members of the tutorial team. Create samples of honest, fair, and constructive feedback that would be appropriate for each of the scores in the table below. Score 0/4 Sample comments 1/4 2/4 3/4 4/4

Consider this scenario and then respond to the prompts below in the spaces provided. (9 marks) *

Scenario: You are at a social gathering and you overhear a few classmates discussing pranks for Engineering week. You join the conversation, and at first the ideas that everyone is sharing sound both funny and harmless so you agree to work with these classmates to design and implement a prank. On the day of the prank, another colleague joins your group and you discover that they have changed the plan in such a way that makes the prank dangerous (i.e. it could result in injury). Additionally you feel there is a risk of property damage, and any incident would certainly cause reputational damage to the Faculty and the University. You now find yourself in an ethical dilemma.

a) State the nature of the dilemma b) List 3 courses of action that you could take and for each action specify the risks and consequences to you, the other members of the group, and the general public Page 8 of 11

  c) Identify the most relevant tenet of the UBC Engineering Code of Ethics (see front of exam) that you would draw on to help you choose a course of action. Justify your choice. d) Identify tools or strategies that you could use to help you decide what to do Page 9 of 11

                       

17.

In the space below, write an elevator pitch for your team’s solution to the Cardboard Chair project, to be presented to another team. Your pitch must be contained in the box below, so carefully plan out what you are going to write before you start (use the blank space at the end of the exam for personal notes). (8 marks) * 18.

Consider this scenario that was discussed in class, and then answer the questions that follow:

A team is designing a cardboard bed for emergency response. The following target design specifications have been identified:

o o o o o o

The bed shall be made only of cardboard The bed shall use no more than 3 m 2 of cardboard, but less is better The bed shall support at least 100 kg, but optimally 200 kg or more The bed shall have a length of at least 2.0 m, but optimally 2.5 m or more The bed can be assembled in a maximum time of 5 minutes, but less is better The bed shall have a height off the ground between 0.15 and 0.25 m Stakeholders have said their primary concern is minimizing the amount of cardboard used per bed. The team generated six ideas (A, B, C, D, E, F) during concept generation. After screening, the team immediately constructs the following WDM.

Criterion  Weight  Cardboard used  Weight supported  Length  Time to assemble  35%  20%  20%  15%  Height off ground  5% 

Weighted Score: 

Concept A  Concept B  Concept C  Raw  Score  Raw  Score  Raw  Score  5  10  1.75  2.0  8  5  2.8  1.0  9  0  3.15  0.0  8  2  7

Page 10 of 11

a) Why do Concepts D, E, and F most likely not appear in the WDM? Explain. b) What do the raw scores for “weight supported” tell you about the actual weight capacity (in kg) of Concepts A and C? Why? c) What is the

MOST

significant error the team has made in the WDM? Why? (Note: you may assume all scores and weighted scores have been accurately computed – no need to check the math.) d) What would you recommend the team do next with Concepts A, B, and C based solely on the weighted scores in this WDM? Why? e) Assuming the team fixes any errors in the WDM, re-computes the scores, and gets similar results to above. What would you recommend the team do next in their design process? Explain.
