On a thin-walled tank, internally pressurized cylinders p with wall thickness t and average radius r, two strain gauges are installed according to the figure in such a way that longitudinal strain gauge (1) and peripheral strain gauge (2) are installed on the tank. Are. Strain gauges are both similar to the Gage factor G and have an electrical resistance of Ro at zero strain. The modulus of elasticity of the tank is E and its Poisson's ratio is 9. Two strain gauges are mounted on two branches of one Watson bridge and two resistors R3 and R4 with similar resistance and constant R on the other two branches of the bridge (as shown in Figure 3). Longitudinal (o,) and peripheral stresses (o9) in a reservoir can be calculated from the following equations: pr 2t pr t It is desirable to calculate the relationship between the internal pressure of the tank p and the output voltage of the Watson bridge vo. 2 Ve R3 RA Figure 1: Thin-walled cylindrical tank under internal pressure p and
