Stress in Flat Blade Solution

Follow our step by step solution on how to calculate Stress in Flat Blade?

FIRST Step Consider the formula

f = (F m) \cdot \frac{0.75 \cdot R b - R h}{b t \cdot {b w}^{3}} / (6)

Next Step Substitute values of Variables

∴

f = (85N) \cdot \frac{0.75 \cdot 75mm - 22mm}{1.5mm \cdot {20mm}^{3}} / (6)

Next Step Convert Units

∴

f = (85N) \cdot \frac{0.75 \cdot 0.075m - 0.022m}{0.0015m \cdot {0.02m}^{3}} / (6)

Next Step Prepare to Evaluate

∴

f = (85) \cdot \frac{0.75 \cdot 0.075 - 0.022}{0.0015 \cdot {0.02}^{3}} / (6)

Next Step Evaluate

∴

f = 40434027.7777778Pa

Next Step Convert to Output's Unit

∴

f = 40.4340277777778N/mm²

LAST Step Rounding Answer

∴

f = 40.434N/mm²

How to Evaluate Stress in Flat Blade?

Stress in Flat Blade evaluator uses Stress in Blade = (Force)*(0.75*Radius of Impeller Blade-Radius of Hub)/(Blade Thickness*Blade Width^(3))/(6) to evaluate 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.

How to evaluate Stress in Flat Blade using this online evaluator? To use this online evaluator for Stress in Flat Blade, enter Force (F_m), Radius of Impeller Blade (R_b), Radius of Hub (R_h), Blade Thickness (b_t) & Blade Width (b_w) and hit the calculate button.

FAQs on Stress in Flat Blade

What is the formula to find Stress in Flat Blade?

The formula of Stress in Flat Blade is expressed as Stress in Blade = (Force)*(0.75*Radius of Impeller Blade-Radius of Hub)/(Blade Thickness*Blade Width^(3))/(6). Here is an example- 4E-5 = (85)*(0.75*0.075-0.022)/(0.0015*0.02^(3))/(6).

How to calculate Stress in Flat Blade?

With Force (F_m), Radius of Impeller Blade (R_b), Radius of Hub (R_h), Blade Thickness (b_t) & Blade Width (b_w) we can find Stress in Flat Blade using the formula - Stress in Blade = (Force)*(0.75*Radius of Impeller Blade-Radius of Hub)/(Blade Thickness*Blade Width^(3))/(6).

What are the other ways to Calculate Stress in Blade?

Here are the different ways to Calculate Stress in Blade-

Stress in Blade=((Maximum Bending Moment)/((Blade Thickness)*(Blade Width)^(2)/(6)))

Can the Stress in Flat Blade be negative?
