Shear Strength of Key Solution

STEP 0: Pre-Calculation Summary

Formula Used

Tangential Force = (Length of Key)*(Width of Key)*Shear Stress in the Key
F = (l)*(b_k)*f_s
This formula uses 4 Variables

Variables Used

Tangential Force - (Measured in Newton) - The Tangential force is the force that acts on a moving body in the direction of a tangent to the curved path of the body.
Length of Key - (Measured in Meter) - The Length of Key is defined as the length of the key which is used to prevent rotation of a machine component or it is the major dimension of the key.
Width of Key - (Measured in Meter) - Width of Key is defined as the width of the key that is fixed in between the shaft and the hub to prevent relative movement between a power transmitting shaft and an attached component.
Shear Stress in the Key - (Measured in Pascal) - Shear Stress in the Key a key is utilized as a part of transmitting torque from a pole to a rotor or center, the accompanying two sorts of strengths follow up on the key.

STEP 1: Convert Input(s) to Base Unit

Length of Key: 35 Millimeter --> 0.035 Meter (Check conversion here)
Width of Key: 5 Millimeter --> 0.005 Meter (Check conversion here)
Shear Stress in the Key: 10 Newton per Square Millimeter --> 10000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = (l)*(b_k)*f_s --> (0.035)*(0.005)*10000000

Evaluating ... ...

F = 1750

STEP 3: Convert Result to Output's Unit

1750 Newton --> No Conversion Required

FINAL ANSWER

1750 Newton <-- Tangential Force

Length of Key based on Crushing Stress in Key

Go Length of Key = (Tangential Force*2)/(Crushing Stress in Key*Thickness of Key)

Thickness of Key based on Crushing Stress

Go Thickness of Key = (Tangential Force*2)/(Crushing Stress in Key*Length of Key)

Crushing Strength of Key

Go Tangential Force = (Length of Key)*(Thickness of Key/2)*Crushing Stress in Key

Crushing Stress in Key

Go Crushing Stress in Key = (Tangential Force*2)/(Thickness of Key*Length of Key)

Shear Strength of Key

Go Tangential Force = (Length of Key)*(Width of Key)*Shear Stress in the Key

Tangential Force at Circumference of Shaft

Go Tangential Force = Maximum Torque/(Diameter of Shaft/2)

Length of Rectangular Key

Go Length of Key = 1.5*(Diameter of Shaft)

Length of Square Key

Go Length of Key = 1.5*(Diameter of Shaft)

Shear Strength of Key Formula

Tangential Force = (Length of Key)*(Width of Key)*Shear Stress in the Key
F = (l)*(b_k)*f_s

What is the main function of Keys?

Shafts and hubs are usually fastened together by means of keys. The main function of a key is to transmit the torque preventing relative motion between a shaft and a machine part assembled on it. Keys are used as temporary fasteners which can be easily disassembled. Keys are subjected to considerable crushing and shearing stresses.

How to Calculate Shear Strength of Key?

Shear Strength of Key calculator uses Tangential Force = (Length of Key)*(Width of Key)*Shear Stress in the Key to calculate the Tangential Force, The Shear Strength of Key formula is defined as its ability to resist forces that cause the material's internal structure to slide against itself. The shear strength of a material can be measured in either the vertical or horizontal direction. Tangential Force is denoted by F symbol.

How to calculate Shear Strength of Key using this online calculator? To use this online calculator for Shear Strength of Key, enter Length of Key (l), Width of Key (b_k) & Shear Stress in the Key (f_s) and hit the calculate button. Here is how the Shear Strength of Key calculation can be explained with given input values -> 1750 = (0.035)*(0.005)*10000000.

FAQ

What is Shear Strength of Key?

The Shear Strength of Key formula is defined as its ability to resist forces that cause the material's internal structure to slide against itself. The shear strength of a material can be measured in either the vertical or horizontal direction and is represented as F = (l)*(b_k)*f_s or Tangential Force = (Length of Key)*(Width of Key)*Shear Stress in the Key. The Length of Key is defined as the length of the key which is used to prevent rotation of a machine component or it is the major dimension of the key, Width of Key is defined as the width of the key that is fixed in between the shaft and the hub to prevent relative movement between a power transmitting shaft and an attached component & Shear Stress in the Key a key is utilized as a part of transmitting torque from a pole to a rotor or center, the accompanying two sorts of strengths follow up on the key.

How to calculate Shear Strength of Key?
