non-working model
who knows?
a working model
None of the above
In science, you first form a hypothesis; in engineering, you first
build a prototype
define a problem
identify criteria
none of the above
When finding the solution to an engineering design problem, there is/are usually

none of the above
_________ is a rigid body transformation that moves objects without deformation.
Rotation
Scaling
Translation
All of the mentioned
The basic geometric transformations are
Translation
Rotation
Scaling
All of the mentioned
In 2D-translation, a point (x, y) can move to the new position (x’, y’) by using the equation
x’=x+dx and y’=y+dx
x’=x+dx and y’=y+dy
X’=x+dy and Y’=y+dx
X’=x-dx and y’=y-dy
To generate a rotation , we must specify
Rotation angle ϴ
Distances dx and dy
Rotation distance
All of the mentioned
A translation is applied to an object by :
Repositioning it along with a straight-line path
Repositioning it along with a circular path
Repositioning it along with an elliptical path
All of these
To change the position of a circle or ellipse we translate :
Center coordinates
Center coordinates and redraws the figure in a new location
Outline coordinates
All of these

circles
all of the mentioned
The process in which the detailed specifications materials, dimensions, tolerances and surface rough is made is known as
decision process
analysis process
implementation process
refinement process
The term that is used for geometric modelling like solid modelling, wire frame modelling and drafting is known as
software package
operating system
application software
none of the mentioned
CAE stands for
