Radius of disc given stresses on disc Formula Elements

Variables
Disc Radius
Disc Radius is a radial line from the focus to any point of a curve.
Symbol: rdisc
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Increase in radius
Increase in radius is the increase in inner radius of outer cylinder of compound cylinder.
Symbol: Ri
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Circumferential Stress
Circumferential Stress is the force over area exerted circumferentially perpendicular to the axis and the radius.
Symbol: σc
Measurement: StressUnit: N/m²
Note: Value should be greater than 0.
Poisson's Ratio
Poisson's Ratio is defined as the ratio of the lateral and axial strain. For many metals and alloys, values of Poisson’s ratio range between 0.1 and 0.5.
Symbol: 𝛎
Measurement: NAUnit: Unitless
Note: Value should be between -1 to 10.
Radial Stress
Radial Stress induced by a bending moment in a member of constant cross section.
Symbol: σr
Measurement: PressureUnit: N/m²
