Physical Properties
What are physical properties?
Characteristics of materials, such as mass and density.
What is CAD?
Computer-Aided Design, a software used for creating precise drawings.
Define an acute triangle.
A triangle with all angles less than 90 degrees.
What is dimensional analysis?
A technique that ensures all necessary dimensions for a part are included.
What is a histogram?
A graph representing the frequency distribution of a data set.
Why are physical properties important?
They ensure functionality and performance in product design.
What is a key advantage of CAD?
It is easily modified and reproducible.
What is a centroid?
The geometric center of a solid.
How do you calculate volume?
Volume is calculated using V=πr2h
Define standard deviation.
A measure of the spread of data values.
Name a characteristic of materials.
Examples include mass, density, and thermal conductivity.
How does CAD improve design accuracy?
It improves accuracy by reducing human error.
What is a tangent?
A line that intersects a circle or arc at one point only.
How do you find surface area?
Surface area can be calculated using SA = 2(wd + wh + dh).
What is normal distribution?
Describes the distribution of variables as a symmetrical bell-shaped graph.
How does material choice impact design?
It affects weight, density, and durability.
Name a disadvantage of traditional drawing.
Traditional drawing can be time-consuming and less accurate
Define a right triangle.
A triangle that has a 90-degree angle.
What is the formula for weight?
Weight is calculated using W = V x Dᵥᵥ
What does "mode" refer to?
The value that occurs most frequently in a data set.
What is the relationship between density and weight?
Density relates to weight by describing mass per volume.
How does CAD allow for 3D visualization?
CAD allows for 3D visualization from multiple angles.
What is an obtuse triangle?
A triangle with one angle greater than 90 degrees.
How do you convert units?
Convert using the appropriate conversion factor.
How is range calculated?
The difference between the largest and smallest values in a data set.
