Thickness of Key based on Crushing Stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Thickness of Key - (Measured in Millimeter) - The thickness of key is usually taken equal to one-sixth of diameter of shaft.
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.
Crushing Stress in Key - (Measured in Newton per Square Millimeter) - Crushing Stress in Key for the material is double the permissible shear stress.
Length of Key - (Measured in Millimeter) - 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
Crushing Stress in Key: 14.8 Newton per Square Millimeter --> 14.8 Newton per Square Millimeter No Conversion Required
Length of Key: 35 Millimeter --> 35 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t = (F*2)/(f_c*l) --> (236.6*2)/(14.8*35)

Evaluating ... ...

t = 0.913513513513514

STEP 3: Convert Result to Output's Unit

0.000913513513513514 Meter -->0.913513513513514 Millimeter (Check conversion here)

FINAL ANSWER

0.913513513513514 ≈ 0.913514 Millimeter <-- Thickness of Key

What is Crushing Stress?

Crushing stress, also known as compressive stress, is a mechanical stress that occurs when a material is subjected to a force or load that acts to compress or crush it. It is the stress experienced by a material when it is pushed or squeezed, causing it to decrease in volume or become more compact. Crushing stress is the opposite of tensile stress, which occurs when a material is subjected to a stretching or pulling force. When a material is under crushing stress, its molecules or particles are pushed closer together, and this stress can lead to deformation, failure, or structural damage if the material's strength is exceeded.

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 Thickness of Key based on Crushing Stress?

Thickness of Key based on Crushing Stress calculator uses Thickness of Key = (Tangential Force*2)/(Crushing Stress in Key*Length of Key) to calculate the Thickness of Key, The Thickness of Key based on Crushing Stress refers to the minimum required thickness of a key used in a mechanical connection, such as a shaft and a hub, to prevent it from being crushed or sheared due to excessive compressive forces. Thickness of Key is denoted by t symbol.

How to calculate Thickness of Key based on Crushing Stress using this online calculator?
