Average Length of a Molecule between Cross-Links

2 Average Length of a Molecule between Cross-Links 

Consider a freely jointed chain with n links, each of vector length f,. The vector end-to-end 

For a large number of chains (q), or one chain considered at many different times, the 

We follow the procedure used, for example, with sinusoidally varying quantities such as alternating current and voltage, where the mean value is zero, and calculate the mean 

The root mean square chain length is then
