Wrench Torque Required to Create Required Pre Load Solution

Follow our step by step solution on how to calculate Wrench Torque Required to Create Required Pre Load?

FIRST Step Consider the formula

M t = 0.2 \cdot P i \cdot d

Next Step Substitute values of Variables

∴

M t = 0.2 \cdot 16500N \cdot 15mm

Next Step Convert Units

∴

M t = 0.2 \cdot 16500N \cdot 0.015m

Next Step Prepare to Evaluate

∴

M t = 0.2 \cdot 16500 \cdot 0.015

Next Step Evaluate

∴

M t = 49.5N*m

LAST Step Convert to Output's Unit

∴

M t = 49500N*mm
