APSC 101 Midterm

Severity

Severity

the maximum harm that could result from an incident

Likelihood

the probability of a harm-causing incident occurring

Hazard

the capacity of something to cause harm (in terms of safety)

Risk

the possibility of harm occurring, determined based on the product of severity and likelihood

3 Risk Sources

Preventable, Strategic, External

5 Risk Types

Safety, Technical, Project Management, Organizational, Market

Preventable

risks to be minimized and within and engineer’s or organization’s control

Strategic

risks knowingly accepted with the hopes of greater return or reward

External

Risk outside an organization’s control, but that still need to be considered and accounted for

Safety

Relating to health and welfare of people and the environment

Technical

Relating to design and manufacture to ensure the solutions works as intended

Project Management

Relating to completing a project on time and on budget

Organization

Relating to decision-making and operation of the organization or device

Market

Relating to correctly understanding market needs and competition

Risk Matrix

a tool for quantifying risk based on the product of ratings for severity and likelihood (low numbers for low risk)

4 Ways to Manage Risk

Avoid, mitigate, transfer, accept

Avoid

change what we are doing to remove the risk entirely

Mitigate

take action to minimize the risk likelihood, severity, or both.

Transfer

pass the risk onto someone else

Accept

be willing to live with the consequences of an incident (only appropriate for minor or strategic risks)

Which category of risk is most strongly relating to engineering codes of ethics

safety

Imagine a case in Module 5 where one team member builds two identical claws to bring to competition (the second is in case the first claw breaks). Which area is most directly affected?

Severity

In the risk management process, when a risk is reduced what is the next step and why

Identify risks - any changes could introduce or expose new risks

At which stage(s) in Tuckman's model is/are conflict expected?

At all stages

What are possible benefits of conflict on a team?

It allows for a diversity of opinions and perspectives to be expressed

Two Dimensions of Tuckman’s Stages of Team Development

Team Relationship(polite and uncertain → open and trusting) and Task Completion (no work being completed → good quality and quantity of work produced)

5 Stages of Tuckman’s Stages of Team Development

Forming, storming, norming (or bad norming), performing

Two Dimensions of Conflict Management Styles

Assertiveness, co-operativeness

assertiveness

speaking to have our goals met in a conflict

co-operativeness

seeking to meet the other party’s goals in a conflict

5 Conflict Management Styles

Avoiding, Accommodating, Competing, Compromising, Collaborating

It is possible for two different objects to have the same three visible orthographic views (T/F)

True

What is the name that describes where lines appear to converge to in perspective projection?

Vanishing point

Match Line type with drawing feature: Visible Line (outside edge of parts)

solid

Match Line type with drawing feature: Centreline (ie centre on side view of cylindrical hole)

dash-dot (long-short) line

Centremark( ie middle of circular feature)

‘+’ shape

Projection

the view used to represent a three-dimensional object in two dimensional space

Perspective Projection

a realistic projection in which closer features appear larger, and far away features converge to points in the distance

Isometric Projection

a pictorial drawing projection that looks three-dimensional with the vertical axis of the object drawn vertical on the page and horizontal axes of the object at 30 degrees on the page.

Third Angle Projection (orthographic views have this)

a way of arranging the views of a multiview orthographic drawing with the view above the front view, and the right view to the right of the front view

Hidden Lines

dashed lines on orthographic multi-view drawings used to show features that are not visible

Where does the top view appear on a drawing created using third angle projection?

Directly above the front view

Dimension Line

a line (usually with arrows on the ends) used to show the size or location of a feature on a drawing

Extension Line

a reference line used to identify features on an object and to which a dimension line points; extension lines allow placing dimension lines away from an object

Elements of Title Blocks

1. units of dimensions

2. tolerance of each dimension (think uncertainty)

3. a symbol noting that the drawing layout is in third angle projection

4. who created and checked the drawing and when

5. material the part is made from and quality of the surface finish (aluminum, machined)

6. drawing scale

7. name and number for the drawing

8. current drawing version

Title Block

a section on an engineering drawing used to display critical information (such as drawing scale, name, and measurement units)
