What is solid structure?
object that uses solid construction
to support loads
Explain shear
forces acting in an object as a result of pushes
and/or pulls in the opposite direction; usually results in
rips or tears in an object
Force
A push or pull
Live load
A type of static load caused by the weight of the objects it supports
Main principles of universal design
- Equal
- Flexible
- Simple
- Safe and tolerant of errors
- Ergonomics
What is frame structure?
a network of parts that supports loads
Torsion
internal twisting forces created in an object as
a result of a twisting motion being applied to the object
Gravity
Dynamic load
Any load on a structure that is not caused by gravity
Symmetry
an exact reflection on opposite sides of a
line dividing an object in half
What is shell structure?
a hollow structure with a curved
shape providing high strength and rigidity
Compression
an internal force
that presses or squeezes the
particles of an object together
Mass
The quantity of matter in an object
Load
A force acting on a structure
Line of symmetry
a line that divides an object in
half; helps display symmetry
Explain structural failure
the failure of a structure as a result
of the structure, or part of the structure losing the ability
to support a load
Tension
an internal force pulling the
particles of an object together
Weight
The force of gravity acting downward on an object
Ergonomics
The science of using
the knowledge of human
characteristics to design structures
and systems that are comfortable,
safe, and efficient
Asthetics
the concepts of how visually attractive
or beautiful something is
Universal Design
an arrangement of the components of
a structure or device resulting in the most user-friendly
product possible
External force
A force
acting on an object or
structure from the outside
Dead Load
The type of static load caused by the weight of structure itself
Universal design
an arrangement of the components of
a structure or device resulting in the most user-friendly
product possible
Name the three basic structure forms
- Solid
- Frame
- Shell
