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 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.
