This work uses Monte Carlo simulation to evaluate the relation between force and extension, the specific heat, the stretching strength and the fourth-order cumulants of the order parameter of a three-dimensional (3D) FRC. We simplify some expressions to calculate the thermodynamical quantities. Our results reveal that at low force, the behavior of the mechanical property of the model is the same as that of a free jointed chain (FJC) in both two-dimensional (2D) and 3D cases. But beginning from a moderate force, the two models have different mechanical properties. Moreover, we find th
