The form factors of the energy-momentum tensor can be accessed
via studies of GPDs in hard exclusive reactions. In this talk
we present recent results on the EMT densities in the bag model.
The simplicity and lucidity of this quark model allow us to
investigate many general concepts which have recently attracted
interest, including shear, pressure, radial and tangential forces.
We also present the first study of the D-term of a $N^*$ resonance.
The results from the bag model are theoretically consistent,
and comply with all general requirements.
