Crushing Stress in Key Solution

Follow our step by step solution on how to calculate Crushing Stress in Key?

FIRST Step Consider the formula

f c = \frac{F \cdot 2}{t \cdot l}

Next Step Substitute values of Variables

∴

f c = \frac{236.6N \cdot 2}{0.2mm \cdot 35mm}

Next Step Convert Units

∴

f c = \frac{236.6N \cdot 2}{0.0002m \cdot 0.035m}

Next Step Prepare to Evaluate

∴

f c = \frac{236.6 \cdot 2}{0.0002 \cdot 0.035}

Next Step Evaluate

∴

f c = 67600000Pa

LAST Step Convert to Output's Unit

∴

f c = 67.6N/mm²

How to Evaluate Crushing Stress in Key?

Crushing Stress in Key evaluator uses Crushing Stress in Key = (Tangential Force*2)/(Thickness of Key*Length of Key) to evaluate 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 evaluate Crushing Stress in Key using this online evaluator? To use this online evaluator for Crushing Stress in Key, enter Tangential Force (F), Thickness of Key (t) & Length of Key (l) and hit the calculate button.

FAQs on Crushing Stress in Key
