force
a push or pull
(solid) mass structure
an object that uses solid construction to support loads (a wooden telephone pole)
shell structure
a structure with a hollow, curved shape (a birds beak, soda can)
manufactured structure
human built structure (building, chair)
natural structure
naturally formed structures in the wild (caves)
column
an upright pillar (th elegs of a table or chair)
beam
a long, sturdy piece of metal meant for supporting a roof or floor above
laminate
a flat surface with a layer of plastic or some other protective layer
corrugated
a material, surface or structure shaped into alternate ridges or grooves (the inside layer of cardboard)
properties
a thing or things that belong to people
composite material
a combination of two materials with different physical and chemical bonding
mobile joint
the joints that are capable of moving in a varity of directions (allows mobility)
rigid joint
two metal beams welded together that don’t allow movement
adhesive
able to stick to a surface or object
mass
amount of particles in an object
weight
the force of gravity on an object
structural efficiency
a structure working the way its supposed to
load
a force acted on an object
live load
(motion) load that is always moving
dead load
(not moving) load that doesn’t move
external force
a force that acts on structure from the outside (wind, earthquakes)
internal force
acts between 2 different parts of a structure (blowing up a balloon) (3 DIFF PARTS: TENSION COMPRESSION, TORISION)
tension force
a pull (pulling on a rubber band)
tensile strength
the maximum stress that a material can handle while being stretched or pulled
compression force
a push (pushing clay together, squishing a sponge)
compressive strength
the maximum strength an object can handle while being compresed or squished together
torsion force
twisting
torsion strengh
the maximum strength an object can handle while being twisted
shear force
A force that causes one part of a material to slide past another
shear strength
its ability to ressist forces (like friction)
snap
someting breaking, with a sharp cracking sound
buckle
the sudden change in shape (deformation) of a structural componant under load
twist
to form into a bent, curling, or disorted shape (torsion)
fatigue
extreme tiredness and inability to function due to lack of energy.
stability
the state of being strong/stable
thrust line
connect the point where the resultant of normal stresses for each crossection of the arch located
aesthetics
appreciation of beauty
erganomics
