1. The problem statement, all variables and given/known data

Hello,

Consider a rod of proper length l_{0}. Prove/Show that there is no length contraction if an observer moves perpendicular to the direction of the rod.

2. Relevant equations

l = l_{0}/\gamma

where \gamma is the usual relativistic vector

3. The attempt at a solution
