Abstract: This work focuses on trying to understand the mechanical properties of nucleons, such as mass, angular momentum, pressure, and shear force distribution, in terms of their quark and gluon constituents. In this thesis, we calculate the pressure and shear force distributions using the matrix elements of the energy-momentum tensor, which can be parametrized in terms of gravitational form factors. We employ light-front wavefunctions of a quark state dressed with a gluon at one loop in QCD. This state serves as a perturbative model for a relativistic spin-1/2 composite system with gluonic degrees of freedom. The light-front Hamiltonian approach is utilized along with a two-component formalism in the light-front gauge to handle the constrained fields.
