What are the 7 steps of Engineering Design Process ?

1. Define the problem

2. Research the problem

3. Develop possible solutions

4. Choose the best solution

5. Create a prototype

6. Test and evaluate

7. Communicate

8. Redesign

CHAPTER 4

BEYOND WORDS

CAD

Computer-Aided Design, computer programs that allow engineers to create precise drawings of their design ideas.

SolidWorks

Software program that allow engineers to construct a model in three-dimensional.

ORTHOGRAPHIC DRAWING

Two-dimensional representation of a 3-D object using views of each side of object.

OBLIQUE DRAWING

Front side of the object appears flat in the picture plane and the side and top of the object are a 45-degree angle to the horizontal lines of the front side.

VANISHING POINT

The parallel lines appear to converge on an imaginary point on the horizon is call the vanishing point.

PERSPECTIVE DRAWING

The lines of the object that move away from the viewer converge on an imaginary point

ISOMETRIC DRAWING

All vertical lines are drawn vertically, but all horizontal lines are drawn at 30 degree to the horizontal.

SCALE

Ratio of the size of an object in a drawing to the size of the object in real life.

METRIC SYSTEM

System of measurements in which all of the units are based on multiples of ten.
