|
Define hooks law |
Extension is proportional to force applied provided the limit of proportionality is not exceeded. |
|
|
Define tensile stress |
Stress = force/area |
|
|
Define tensile strain. |
Strain = extension / original length |
|
|
Define young modulus. |
Young modulus = stress/strain The ratio of stress to strain and a measure of the stiffness of a material. |
|
|
Define the elastic limit |
The point which once exceeded the material will deform plastically (permanently). |
|
|
Define density. |
Density = mass/volume Density is the mass of an object per unit of volume. |
|
|
State ohm's law. |
Current is directly proportional to voltage provided the temperature remains constant. |
|
|
Define electromotive force. |
The energy provided by a battery or cell per unit of charge which passes through it. |
