1

what is stress

- internal force opposing the external force on a body

2

what force is acting on us at all times?

gravity

3

what are the 4 types of stress?

1. tension
2. compression
3. torsion
4. shear

4

what is tension?

-act of pulling
-tensile strength

5

what is compression

-act of pushing
-compressive strength

6

what is torsion?

-act of twisting
-torque strength

7

what is shear?

-act of ripping
-shear strength

8

what is the 5th type of stress?

- bend
-combination of stresses, compression and tensile and shear

9

name some example of materials with high tensile strength

-rope wire chains

10

name some example of materials with high compressive strength

- concrete, gravel

11

name some example of materials with high torque strength

screws

12

name some example of materials with high shear strength

wood, bolts, nails

13

what is deformation?

- change in a body of matter whenever a force is applied or acts on the body --> always happens even if you cant see it
