Q
What is the equation for time dependent strength?
A
T = absolute temperature so if temp given in degrees celcius you have to convert to kelvin by adding 273.

Q
What is the equation for tensile strength of a material?
A
3
Q
What is the equation for glass transition temperature?
A
4
Q
What is the equation for the number of vacancies in crystals?
A
5
Q
What is Avogadro’s number?
A
6.02 x 1023
6
Q
What are the equations for bonding forces?
A
FN = FA + FR
FA = -A / r2
FR = B / r9
A and B are just constants, r is the atomic separation.
FA = dEA / dr
FR = dER / dr
To calculate the repulsive/attractive forces you can just differentiate the corresponding energies.
