Shear Stress on Flat Key Solution

STEP 0: Pre-Calculation Summary

Formula Used

Shear Stress = (2*Torque Transmitted by Shaft)/(Width of Key*Diameter of Shaft*Length of Key)
𝜏_{flat key} = (2*T)/(b_k*d_s*l)
This formula uses 5 Variables

Variables Used

Shear Stress - (Measured in Pascal) - Shear Stress is force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress.
Torque Transmitted by Shaft - (Measured in Newton Meter) - Torque Transmitted by Shaft between the two ends of it.
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.
Diameter of Shaft - (Measured in Meter) - The Diameter of Shaft is the diameter of the external surface of a shaft which is a rotating element in the transmitting system for transmitting power.
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

Torque Transmitted by Shaft: 800 Newton Meter --> 800 Newton Meter No Conversion Required
Width of Key: 5 Millimeter --> 0.005 Meter (Check conversion here)
Diameter of Shaft: 1200 Millimeter --> 1.2 Meter (Check conversion here)
Length of Key: 35 Millimeter --> 0.035 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

𝜏_{flat key} = (2*T)/(b_k*d_s*l) --> (2*800)/(0.005*1.2*0.035)

Evaluating ... ...

𝜏_{flat key} = 7619047.61904762

STEP 3: Convert Result to Output's Unit

7619047.61904762 Pascal -->7.61904761904762 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

7.61904761904762 ≈ 7.619048 Newton per Square Millimeter <-- Shear Stress
