Crushing Stress in Key Solution

STEP 0: Pre-Calculation Summary

Formula Used

Crushing Stress in Key = (Tangential Force*2)/(Thickness of Key*Length of Key)
f_c = (F*2)/(t*l)
This formula uses 4 Variables

Variables Used

Crushing Stress in Key - (Measured in Pascal) - Crushing Stress in Key for the material is double the permissible shear stress.
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.
Thickness of Key - (Measured in Meter) - The thickness of key is usually taken equal to one-sixth of diameter of shaft.
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.

STEP 1: Convert Input(s) to Base Unit

Tangential Force: 236.6 Newton --> 236.6 Newton No Conversion Required
Thickness of Key: 0.2 Millimeter --> 0.0002 Meter (Check conversion here)
Length of Key: 35 Millimeter --> 0.035 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_c = (F*2)/(t*l) --> (236.6*2)/(0.0002*0.035)

Evaluating ... ...

f_c = 67600000

STEP 3: Convert Result to Output's Unit

67600000 Pascal -->67.6 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

67.6 Newton per Square Millimeter <-- Crushing Stress in Key

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 Crushing Stress in Key?

Crushing Stress in Key calculator uses Crushing Stress in Key = (Tangential Force*2)/(Thickness of Key*Length of Key) to calculate the Crushing Stress in Key, Crushing Stress in Key is Force Due to the torque transmitting by the shaft results in shearing stress. These stresses cannot be uniform along the length of the key, due to the forces which are concentrated on the torque input end on the shaft to the hub thru the key. Crushing Stress in Key is denoted by f_c symbol.

How to calculate Crushing Stress in Key using this online calculator? To use this online calculator for Crushing Stress in Key, enter Tangential Force (F), Thickness of Key (t) & Length of Key (l) and hit the calculate button. Here is how the Crushing Stress in Key calculation can be explained with given input values -> 6.7E-6 = (236.6*2)/(0.0002*0.035).

FAQ

What is Crushing Stress in Key?

Crushing Stress in Key is Force Due to the torque transmitting by the shaft results in shearing stress. These stresses cannot be uniform along the length of the key, due to the forces which are concentrated on the torque input end on the shaft to the hub thru the key and is represented as f_c = (F*2)/(t*l) or Crushing Stress in Key = (Tangential Force*2)/(Thickness of Key*Length of Key). 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, The thickness of key is usually taken equal to one-sixth of diameter of shaft & 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.

How to calculate Crushing Stress in Key?
