Elasticity Flashcards
1
Q
forces acting on solids
A
tension/compression, bulk stress and strain and shear
2
Q
stress
A
F⊥/A
3
Q
strain
A
ΔL/Lo
4
Q
young’s modulus
A
stress/strain
5
Q
brittle
A
cannot apply a lot of stress/strain
6
Q
ductile
A
can apply stress/strain but past the elastic yield it will deform
7
Q
spring constant
A
k = YA/l
8
Q
Hooke’s Law
A
F = -kx
9
Q
work done
A
W = f*s
10
Q
work done on a stretched spring
A
W = -1/2 kx^2

Q
compressibility
A
k = 1/B
