What is the first step in the PLTW Engineering Design Process?
Generate Concepts
Define the Problem
Develop a Solution
Construct and Test Prototype
In which step of the PLTW Engineering Design Process is a prototype created?
Evaluate Solution
Generate Concepts
Construct and Test
Present Solution
The Engineering Design Process is linear, meaning that each step is only completed once and there is no going back to a previous step.
True
False
Which step in the PLTW Engineering Design Process involves reviewing the test results and identifying areas of improvement?
Present Solution
Evaluate Solution
Generate Concepts
Construct and Test Prototype
You’re working on a popsicle stick bridge and the prototype failed its first test due to weak structural support. Which step should you revisit to improve the design?
Develop a Solution
Evaluate Solution
Generate Concepts
Define the Problem
What is the main purpose of a concept sketch in the engineering design process?
To create a final blueprint
To develop a 3D model
To communicate initial ideas visually
To calculate precise measurements
Concept sketches should be made perfect.
True
False
Concept sketches can be used to illustrate multiple design ideas for the same problem.
True
False
Which of the following best describes how concept sketches help during team collaboration?
They allow everyone to see the exact measurements and specifications.
They provide a common visual reference for brainstorming and discussion.
They eliminate the need for any further drawing or prototyping.
They only benefit the person who created the sketch.
Concept sketches are only used at the beginning of a project and are never revised.
True
False
Which of the following best describes an isometric sketch?
A sketch showing a 2D representation of an object.
A 3D sketch with all lines at 90 degrees.
A 3D sketch with angles between the axes drawn at 120 degrees.
A 2D sketch focusing on one face of an object.
In isometric sketches, horizontal lines are drawn at a 30-degree angle from the baseline.
True
False
Isometric sketches distort shapes to give a realistic 3D appearance.
True
False
When drawing an isometric circle, what shape is actually drawn to represent the circle accurately?
Circle
Square
Ellipse
Triangle
Which of the following steps is NOT involved in creating an accurate isometric circle?
Sketch a square in isometric view to guide the circle’s dimensions.
Draw an ellipse inside the square, touching the midpoint of each side.
Draw a perfect circle directly on the isometric plane.
Use guide points to ensure the ellipse’s accuracy.
