We investigate the strong force fields and stabilities of the nucleon and the singly heavy baryon ${\mathrm{\ensuremath{\Sigma}}}_{c}$ within the framework of the chiral quark-soliton model. Having constructed the pion mean fields in the presence of the ${N}_{c}\ensuremath{-}1$ level quarks self-consistently, we are able to examine the gravitational form factors of ${\mathrm{\ensuremath{\Sigma}}}_{c}$. We mainly focus in the present work on the stability conditions for both the nucleon and ${\mathrm{\ensuremath{\Sigma}}}_{c}$ and discuss the strong force fields and their physical implications. We also present the results for the gravitational form factors and relevant observables, emphasizing the difference between the nucleon and ${\mathrm{\ensuremath{\Sigma}}}_{c}$.
