Maximum Bending Moment for Impeller Blade Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Bending Moment = Force*(0.75*Radius of Impeller Blade-Radius of Hub)
M_m = F_m*(0.75*R_b-R_h)
This formula uses 4 Variables

Variables Used

Maximum Bending Moment - (Measured in Newton Meter) - Maximum Bending Moment is the algebraic sum of the moments caused by the internal forces on the shaft and it causes the shaft to rotate.
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.

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)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_m = F_m*(0.75*R_b-R_h) --> 85*(0.75*0.075-0.022)

Evaluating ... ...

M_m = 2.91125

STEP 3: Convert Result to Output's Unit

2.91125 Newton Meter -->2911.25 Newton Millimeter (Check conversion here)

FINAL ANSWER

2911.25 Newton Millimeter <-- Maximum Bending Moment

(Calculation completed in 00.004 seconds)

Stress in Flat Blade

Go Stress in Blade = (Force)*(0.75*Radius of Impeller Blade-Radius of Hub)/(Blade Thickness*Blade Width^(3))/(6)

Stress in Blade due to Maximum Bending Moment

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

Maximum Bending Moment for Impeller Blade

Go Maximum Bending Moment = Force*(0.75*Radius of Impeller Blade-Radius of Hub)

Maximum Bending Moment for Impeller Blade Formula

Maximum Bending Moment = Force*(0.75*Radius of Impeller Blade-Radius of Hub)
M_m = F_m*(0.75*R_b-R_h)

What is Bending ?

Bending characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. In the quasi-static case, the amount of bending deflection and the stresses that develop are assumed not to change over time.

How to Calculate Maximum Bending Moment for Impeller Blade?

Maximum Bending Moment for Impeller Blade calculator uses Maximum Bending Moment = Force*(0.75*Radius of Impeller Blade-Radius of Hub) to calculate the Maximum Bending Moment, The Maximum Bending Moment for Impeller Blade formula is defined by establishing bending moments which form the blades into sections which are curved and flat, with the flat sections being at least in the center area of the base of the blade. Maximum Bending Moment is denoted by M_m symbol.

How to calculate Maximum Bending Moment for Impeller Blade using this online calculator? To use this online calculator for Maximum Bending Moment for Impeller Blade, enter Force (F_m), Radius of Impeller Blade (R_b) & Radius of Hub (R_h) and hit the calculate button. Here is how the Maximum Bending Moment for Impeller Blade calculation can be explained with given input values -> 2.9E+6 = 85*(0.75*0.075-0.022).
