Who is responsible for designing most products used in today's society?

• Scientists

• Engineers

• Artists

• Teachers

Answer explanation

Engineers are primarily responsible for designing products used in society, as they apply scientific principles to create functional and efficient solutions, unlike scientists, artists, or teachers who focus on different fields.

What is a step of the design process that involves reassessing design specifications?

• Implementation

• Transition

• Optimization

• Evaluation

Answer explanation

Optimization is the step in the design process where design specifications are reassessed to improve performance and effectiveness. This involves refining the design based on feedback and testing results.

What does the diagram of input, process, output, and feedback represent?

• Open-loop system

• Linear process

• Closed-loop system

• Static model

Answer explanation

The diagram represents a closed-loop system because it includes feedback, allowing for adjustments based on the output. This contrasts with an open-loop system, which lacks feedback.

What is the principle of design that involves gradual change?

• Symmetry

• Balance

• Transition

• Contrast

Answer explanation

The principle of design that involves gradual change is called Transition. It refers to the smooth progression from one element to another, creating a sense of movement and flow in the design.

What is the list of topics covered in someone's written work called?

• Index

• Glossary

• Table of contents

• Bibliography

Answer explanation

The correct answer is 'Table of contents' as it specifically lists the topics covered in a written work, helping readers navigate the content. An index is for locating specific information, while a glossary defines terms.

What is an organized collection of your best work called?

• Resume

• Portfolio

• Biography

• Curriculum Vitae

Answer explanation

A portfolio is an organized collection showcasing your best work, often used to demonstrate skills and achievements. Unlike a resume or CV, which summarize qualifications, a portfolio provides tangible examples of your work.

What do section lines represent in engineering drawings?

• Exterior features

• Interior features

• Color schemes

• Material types

Answer explanation

Section lines in engineering drawings indicate interior features of an object, such as the details of a cut or section view. They help visualize the internal structure, making 'Interior features' the correct choice.

Which perspective drawing technique uses two vanishing points?

• One-point perspective

• Three-point perspective

• Two-point perspective

• Isometric perspective

Answer explanation

A two-point perspective drawing uses two vanishing points on the horizon line, allowing for a more dynamic representation of objects in space. This distinguishes it from one-point and three-point perspectives.

What is an oblique drawing?

• A drawing with no depth

• A two-dimensional drawing

• A type of technical illustration representing three dimensions

• A drawing with only horizontal lines

Answer explanation

An oblique drawing is a type of technical illustration that represents three dimensions on a two-dimensional surface, allowing for a clearer understanding of the object's form and structure.

What is a tangent in relation to circles and arcs?

• A line that intersects a circle at two points

• A line that is parallel to a circle

• A line that touches a circle at only one point

• A line that is inside a circle

Answer explanation

A tangent is defined as a line that touches a circle at only one point, making it distinct from other lines that may intersect or be parallel to the circle. Thus, the correct answer is that a tangent touches a circle at one point.
