1
Q
Stress
A
magnitude of force applied to an object per unit
2
Q
Types of stress
A
tensile, compression, shear and volume
3
Q
Stress units
A
S= F/A so N/m^2
4
Q
Strain
A
ratio of the change in length when stress in applied
5
Q
Stress units

dimensionless
6
Q
… on a rod causes a ….
A
stress… strain
7
Q
Tensile Deformation formula
A
td= Young’s modulus x strain
8
Q
Young’s modulus is …
A
the slope of a graph of strain x stress
9
Q
Elastic Limit
A
max stress an object can be put under without permanently deforming
10
Q
Tensile Strength
A
the rod will snap at some tensile strength
11
Q
Compressive Deformation
A
not vertical
causes object to fracture
12
Q
Shear deformation
A
deformed when force is applied tangentially
