What is density? |
Mass/Volume |
|
How do you calculate percentage uncertainty? |
( Instrument precision/measurement )×100 |
|
What is the spring constant, k ? |
A measure of how hard it is to bend or stretch a spring. A large spring constant means that the spring is stiff. Unit N/m |
|
What is the limit of proportionality? |
The endpoint of the linear section of a force-extension graph |
|
What is the elastic limit? |
The load above which a material becomes permenantly deformed |
|
How do you measure elastic strain energy? |
It is the are below a force-extension graph |
|
What is tensile stress? |
Force/Cross sectional area , unit N/m^2 |
|
What is tensile strain? |
Extension/Original Length, m |
|
