Engineering Design and Measurement Notes

Flashcards about engineering design and measurement.

The steps of the _ are: Define Problem, Generate Concepts, Develop Solution, Construct and Test, Evaluate Solution, Present Solution.

design process

The design process is __ - that means each of the steps can be repeated.

iterative

Four major disciplines of engineers are , , , and .

mechanical, chemical, civil, and electrical

__ is a group technique for solving problems and generating ideas. The goal is to come up with a large quantity of ideas, NOT evaluate whether or not the ideas would work.

Brainstorming

A __ is a part of generating and evaluating which idea would be the best based on how it solves different issues and how it follows criteria.

decision matrix

The __ step of the design process would utilize a design brief.

Define Problem

In the __ step of the design process would you create an Inventor model.

Develop Solution

Some guidelines for effective brainstorming are > , Take your time, create __ of ideas.

Quantity > Quality, lots

__ engineering is responsible for wiring a new classroom for outlets and lights.

Electrical

__ engineering is responsible for designing a new air conditioning system to regulate air temperature in the school.

Mechanical

__ engineering is responsible for designing a better vaccination for the flu.

Chemical

__ engineering is responsible for designing a new bridge over I-70.

Civil

Three examples of guidelines you should follow when using an engineering notebook are __, __, __.

Pen, Date, Signature

are new ideas, are improvements

Inventions, innovations

__ sketches show 3 faces at once so they appear 3-dimensional.

Pictorial

__ -quick sketches that are not drawn to scale, front face is straight forward.

Oblique

__-scaled drawings made at 120 or 60 degree angles.

Isometric

__ - the most realistic pictorial sketches because they mimic how our eyes view objects.

Perspective

__ sketches are also known as orthographic projections and show multiple 2-D views of an object.

Multi-view

You determine the best __ view of an object by finding the face that has the most features.

front

The 3 most common views in an orthographic projection are __, __, __.

Top, Front, Side

An __ sketch is used to communicate the shape and size of an object to a manufacturer.

Isometric

A Sketch, is often used in brainstorming.

Concept, Oblique

An __ line is part of the object

object

A __ line is not visible in sketch.

hidden

__ line is used to lines up sketches

construction

A __ is a precision measuring tool. It typically measures in inches down to the ten-thousandths place.

dial caliper

A __ ruler measures in decimals of centimeters.

metric

A __ ruler measures in fractions of inches.

US customary

All measurements have 3 things - a __, __, and __.

value, unit, uncertainty

__ in a measurement refers to how close a measurement is to an accepted value and precision refers to how reproducible a measurement is.

Accuracy

A __ is a fraction where the measurement on the top and bottom of a fraction are equivalent.

conversion factor

In a __ -step conversion, the desired unit goes on top of the conversion factor and the given unit goes on the bottom.

one

__measure the middle of a data set.

Central tendencies

Data that is normally distributed produces a __ where the mean of the data set is at the top of the curve and both the left and right sides slope down symmetrically.

bell curve

A __ refers to a measurement where every value in the group is measured and a sample is where only part of a group is measured.

population
