Diagonal Lines used as a visual design element represent action and movement. What do vertical lines represent?
stability and strength
A CAD operator needs to represent the size of a rectangular slot, d2, so that the size is always 75% larger than the hole diameter, d1.
d2 = 1.75*d1
The image below represents what Element of Design
positive/negative space
Use the images below to answer the question. Which image above shows unilateral tolerance?
image B
Convert 6.0 quarts to liters, rounded to two significant figures.
5.7L
What is the Visual Design Element that enables the designer to use the color blue to represent cool, calm emotion and the red, orange or yellow to represent warmth or excitement?
Color
Spring:
A spring has a natural length of 15 centimeters. When a force of 37.5 newtons is applied to the spring, it stretches to a length of 30 centimeters. The displacement of the spring can be represented by “x” centimeters, and the applied force can be represented by “F” newtons.
Hooke’s Law:
f(x) = kz
F = applies force
K = spring constant
x = displacement
F(spring) = - F(applied Force)
What is the value of displacement in cm?
15
Spring:
A spring has a natural length of 15 centimeters. When a force of 37.5 newtons is applied to the spring, it stretches to a length of 30 centimeters. The displacement of the spring can be represented by “x” centimeters, and the applied force can be represented by “F” newtons.
Hooke’s Law:
f(x) = kz
F = applies force
K = spring constant
x = displacement
F(spring) = - F(applied Force)
If we conduct a experiment and stretch the spring to a length of 35 cm, how much applied force is needed? Write value only.
50
Spring:
A spring has a natural length of 15 centimeters. When a force of 37.5 newtons is applied to the spring, it stretches to a length of 30 centimeters. The displacement of the spring can be represented by “x” centimeters, and the applied force can be represented by “F” newtons.
Hooke’s Law:
f(x) = kz
F = applies force
K = spring constant
x = displacement
F(spring) = - F(applied Force)
In the experiment we conducted above, which variable is the independent variable that we can manipulate?
displacement of the spring
In reverse engineering what is the purpose of a functional analysis
To identify the purpose, functions and inputs/outputs
What is the purpose of a decision matrix in a design process?
Evaluates and prioritizes a list of options
Empirical Rule:
A group of engineering students conducted a study on the efficiency of a manufacturing process. THey collected data on the number of defective products produced in a sample of 200 production runs. The mean number of a defective products was found to be 10, with a standard deviation of 2.
Within what range of values would expect app 95% of the productions runs to fall in ters of the number of defective products?
6 <= x <= 14
