Radial stress at center of solid disc Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radial Stress = (Density Of Disc*(Angular Velocity^2)*(3+Poisson's Ratio)*(Outer Radius Disc^2))/8
σ_r = (ρ*(ω^2)*(3+𝛎)*(r_outer^2))/8
This formula uses 5 Variables

Variables Used

Radial Stress - (Measured in Pascal) - Radial Stress induced by a bending moment in a member of constant cross section.
Density Of Disc - (Measured in Kilogram per Cubic Meter) - Density Of Disc shows the denseness of disc in a specific given area. This is taken as mass per unit volume of a given disc.
Angular Velocity - (Measured in Radian per Second) - The Angular Velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time.
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.
Outer Radius Disc - (Measured in Meter) - Outer Radius Disc is the radius of the larger of the two concentric circles that form its boundary.

STEP 1: Convert Input(s) to Base Unit

Density Of Disc: 2 Kilogram per Cubic Meter --> 2 Kilogram per Cubic Meter No Conversion Required
Angular Velocity: 11.2 Radian per Second --> 11.2 Radian per Second No Conversion Required
Poisson's Ratio: 0.3 --> No Conversion Required
Outer Radius Disc: 900 Millimeter --> 0.9 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_r = (ρ*(ω^2)*(3+𝛎)*(r_outer^2))/8 --> (2*(11.2^2)*(3+0.3)*(0.9^2))/8

Evaluating ... ...

σ_r = 83.82528

STEP 3: Convert Result to Output's Unit

83.82528 Pascal -->83.82528 Newton per Square Meter (Check conversion here)

FINAL ANSWER

83.82528 Newton per Square Meter <-- Radial Stress
