Appl, [4] Batista ,M. and Usenik, Stresses in a circular ring under two forces acting along a diameter, J. Strain analysis, 1996,31 (1), [5] Ma,D., `Elastic stress solution for a ring subjected to es. & Piping, 1990, [6] Ma,D., `Elastic stress solution for a ring subjected to loaded rings , which were put forward in the past by a lot of authors, are presented in these paper. In the future design of rings and their force sensors, the suitable computing formulas are chosen. It is significant for instruction to design rings and their force sensors. In addition , the positions of maximum circumferential stress ,where the strain strips should be stick, are recommended, when the force ring sensors are studied. Keywords ：force sensors; loaded rings; stress calculations
