100
The systematic problem solving strategy used to develop many possible solutions.
What is the design process?
100
A form of pictorial drawing in which all three drawing axes form equal angles of 120 degrees. This type of drawing is drawn at 30 degrees.
What is an isometric drawing and what angle is it drawn at?
100
Define the center of arcs, circles or symmetrical parts. Half the thickness of object lines.
What are center lines?
100
Constrains a cylinder flush into a hole.
What does the assembly constraint insert do?
100
The degree to which repeated measurements show the same results. The degree of closeness of measurements of a quantity to actual value.
What is the difference between precision and accuracy?
200
1. Define the Problem 2. Generate Concepts 3. Develop a Solution 4. Construct and Test a Prototype 5. Evaluate Solution 6. Present Solution
What are the steps of the design process?
200
Cavalier is drawn at full scale and cabinet is drawn at half scale.
What are the two different types of oblique drawings and what is the difference between them?
200
Show interior design; not visible from outside of part.
What are hidden lines?
200
Constrains two faces or edges at an angle to each other.
What does the assembly constraint angle do?
200
A measuring instrument having two adjustable jaws; typically used to measure diameter. More precise than a ruler and goes to thousandths place.
What is a dial caliper?
300
1. One conversation at a time 2. Differ judgement 3. Stay focused 4. Encourage wild ideas 5. Build upon the ideas of others
What are the rules of brainstorming?
300
A form of pictorial drawing that contains the views of an object projected on two or more orthographic planes. Also known as right angle projection.
What is a multi view/ orthographic drawing?
300
Define where material is cut away.
What are section lines?
300
Contrains two faces, edges, points or axes together. Constrains two faces, edges, points or work features together with geometry side by side.
What is the difference between the assembly constraints mate and flush?
300
A book in which an engineer will formally document all work related to a design project. Patents activities like proving the origin of an idea, prove when events occurred, and prove diligence when presenting a solution. Numbered, dated, signed by witness, statement of proprietary and nature of notebook.
What is an engineering notebook, its use and the parts of each page?
400
Step 1: Define the problem; Design brief. Step 2: Research; brainstorm; decision matrix. Step 3: Create technical drawings. Step 4: Build a prototype; design testing; test report Step 5: Optimize Designs; revise drawings; project recommendation Step 6: Project portfolio; formal presentation
What are the activities of each step of the design process?
400
A form of pictorial drawing in which an object has it's true width and height, but depth is any size of angle. Drawn at 30, 45 or 60 degrees.
What is an oblique drawing and what angle is it drawn at?
400
Imaginary lines used to project corners, edges and features of 3D objects on 2D surfaces.
What are projection lines?
400
Constrains a curved surface to a plane or another curved surface.
What does the geometry constraint tangent do?
400
Means of judging. A limit to a design process.
What is the difference between criteria and constraint?
500
1. Client/End User/ Target Consumer 2. Problem Statement 3. Design Statement
What are the sections of a design brief?
500
1. Most natural position 2. Shows best shape and characteristic contours 3. Longest dimensions 4. Fewest hidden lines 5. Stable
What are the requirements for selecting the front view of an object?
500
Show where a dimension starts and ends. Show distance and have arrows on the end.
What is the difference between dimension and extension lines?
500
Constrains two points together and causes a point to lie on a curve. Makes two lines lie in a straight line with each other. Causes 2 arcs, circle or ellipses to have the same center point.
What is the difference between the geometric constraints coincident, collinear and concentric?
500
The variables by which an object can move; movement on the x, y and z axis. 6 degrees. Linear and rotational.
What is the degrees of freedom, how many does an object start with and what are the two types of movement on each axis?
