Stress in Flat Blade Solution

STEP 0: Pre-Calculation Summary

Formula Used

Stress in Blade = (Force)*(0.75*Radius of Impeller Blade-Radius of Hub)/(Blade Thickness*Blade Width^(3))/(6)
f = (F_m)*(0.75*R_b-R_h)/(b_t*b_w^(3))/(6)
This formula uses 6 Variables

Variables Used

Stress in Blade - (Measured in Pascal) - Stress in Blade is related to mechanical loading directly and satisfies force and moment equilibrium. Primary stress that exceeds the yield stress by some margin will result in failure.
Force - (Measured in Newton) - Force is a push or pull upon an object resulting from the object's interaction with another object.
Radius of Impeller Blade - (Measured in Meter) - Radius of Impeller Blade is known for the blade which is situated from its center point.
Radius of Hub - (Measured in Meter) - Radius of Hub is usually taken as half the diameter of shaft and length from 4 to 5 times the shaft diameter.
Blade Thickness - (Measured in Meter) - Blade Thickness is generally determined by the blade width and the wider the blade, then the thicker the material that it's made from.
Blade Width - (Measured in Meter) - Blade Width is measured from the tooth tip to the back edge of the blade.

STEP 1: Convert Input(s) to Base Unit

Force: 85 Newton --> 85 Newton No Conversion Required
Radius of Impeller Blade: 75 Millimeter --> 0.075 Meter (Check conversion here)
Radius of Hub: 22 Millimeter --> 0.022 Meter (Check conversion here)
Blade Thickness: 1.5 Millimeter --> 0.0015 Meter (Check conversion here)
Blade Width: 20 Millimeter --> 0.02 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f = (F_m)*(0.75*R_b-R_h)/(b_t*b_w^(3))/(6) --> (85)*(0.75*0.075-0.022)/(0.0015*0.02^(3))/(6)

Evaluating ... ...

f = 40434027.7777778

STEP 3: Convert Result to Output's Unit

40434027.7777778 Pascal -->40.4340277777778 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

40.4340277777778 ≈ 40.43403 Newton per Square Millimeter <-- Stress in Blade

What is Stress?

When a shaft is subjected to a torque or twisting a shearing stress is produced in the shaft. The shear stress varies from zero in the axis to a maximum at the outside surface of the shaft. the "Polar Moment of Inertia of an Area" is a measure of a shaft's ability to resist torsion.

How to Calculate Stress in Flat Blade?

Stress in Flat Blade calculator uses Stress in Blade = (Force)*(0.75*Radius of Impeller Blade-Radius of Hub)/(Blade Thickness*Blade Width^(3))/(6) to calculate the Stress in Blade, Stress in Flat Blade formula is defined as the stress distribution in the flat blade due to action of all forces such as gas and centrifugal forces. It is observed that the maximum stress of 1.958 GPa occurs at the root section and on the pressure side of gas turbine flat blade. Stress in Blade is denoted by f symbol.
