The mass density is p=30000kg/m³, the link thickness T is 0.02 m, the joint shaft and hole diameter is 0.025 m, and the link radius is 0.02 m. There is an external torque (t N.m) on one of the links, applied at the centre of mass on one of the links, and at the same time an external force of F, acts on link 5, applied at point p and lf [m] away from point A.
