Lesson 2- elasticity Flashcards
Main aspect of this lesson
Hookes law!
Add formula:
Add classifications of the materials
Nonisotropic: to the bones
break bones: perpendicular (up)
Stress and strain are proportional.
OBS should know. Mechanical deformations of bines depening on the type of load. Today about bending.
formula of defotmation
L: length between resting points
Deformation to applied force should be somewhat linear
Gpa: 2x10 power of 11 for 200
2x10 power of 9 for giga?
measure h using device on top
One measurement with loading and one with unloadin- vill get difference. Get average from 2 volumes. Press on
With wood, compare value to wood in graph if.
take fake linjal and measure ra
inside of pillars, will be the …
error margin 0.01
obs - på ?
3- 10.02 cm
enter slope value 0,00032x + 0,0000
isntead of e below, use slope of the graph instrad
siffran före x är gjord för theoretical E

Why learn elasticity?
Find right biomaterial for e.g. replacement.
Different biomaterials.
Look at the different properties
