transition fit

Answer 7

sometimes have a clearance and interference fit

Question 8

allowance

Answer 8

minimum clearance or maximum interference between parts. for clearance the allowance is the smallest space. for interference allowance is negative and represents maximum interference. smallest hole - largest pin

Answer 14

sliding linearly on an axis restricting rotational movement

Question 15

cylindrical

Answer 15

one translational and one rotational degree of freedom between two connected parts

Question 16

pin-slot

Answer 16

allows both translation and rotation between two connected components around a specific point

Question 17

Question 20

7 Visual design principles

Answer 20

balance (symmetry), emphasis (draw attention to one area), contrast (difference between two elements), rhythm (patterns), proportion (comparing size), unity (consistent use of elements), and economy (simplicity)

pear, hexagonal, eccentric, circular, heart, snail

Question 26

What does a design brief include? (list each step and explain) What step in the design process does it fall in?

Answer 26

Client - Defines who the product is presented to Engineer - Who designed the product Problem Statement - Defines the problem Design Statement - Defines how the product will fix the problem - Develop a Solution Constraints - Identifies limits of the design - Develop a Solution Criteria - something that the thing must have

Question 27

difference between criteria and constraints

Answer 27

criteria define the goals and standards that a solution must meet, while constraints are limitations or restrictions that influence the design process

Question 28

engineering

Answer 28

the branch of science and technology concerned with the design, building, and use of engines, machines, and structures

What is the purpose of an auxiliary view?

Answer 31

To show detail that a regular multiview can't

Question 32

How is an auxiliary view different from a multiview projection?

Answer 32

An auxiliary view provides a view by cutting the shape, while a multiview projection just rotates it.
