Hi,
Can somebody give me an example of a rank 4 tensor in physics? Thanks.

Sure, one would be the Riemann curvature tensor R_{ijkl} that's used in general relativity.

Thanks.
It was an odd small part of an exam question when my module had only covered examples up to 3rd rank.

4th rank Tensor
Third order nonlinear susceptibility is another example of 4th rank tensor.
