  We compute the mass radius, scalar radius, tensor radius, baryon number
radius and mechanical radius of nuclei with baryon number
$B=1,2,3,4,5,6,7,8,32,108$ in the Skyrme model. The relations between these
radii and the nuclear gravitational form factors are investigated. We also
compute the `pressure' distribution and find that it is negative in the core
region for all the nuclei with $B>1$. This suggests that the way mechanical
stability is achieved in nuclei is qualitatively different than in the nucleon.
