| 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, |
