compression | squeezing, pushing, pressing. eg. step on a bug and kill it |
dynamic loads | loads that change or move around. |
bending | squeezing + pulling; compression + tension; eg. make the stick into a bow |
torsion | twisting; squeeze + pull; compression + tension; eg. twist the water from the towel |
shear | separating force put from opposite directions; eg. cut paper with scissors |
gusset | triangular or other shaped brace for making a corner stronger to join parts |
strut | It resists compression. (against squeezing) eg. mattress |
tie | It resists tension (against pulling) eg. spring scale |
truss | It has a group of triangular frames. eg. frames on a bridge |
structure | It has parts that has a purpose. can be human made, made by other living things or natural things like cave made by wind ... water, |
load | weight, mass or force put to a structure. |
purpose of structures | support, shelter, contain, direct, transport |
transport | move |
direct | control the flow of something |
contain | hold something in |
shelter | hold something out |
support | hold something up |
static loads | they are loads that don't move. |
tension | pulling, stretching; eg. tug of war |
