Coefficient of Friction at Collar of Screw according to Uniform Wear Theory Solution

Follow our step by step solution on how to calculate Coefficient of Friction at Collar of Screw according to Uniform Wear Theory?

FIRST Step Consider the formula

μ collar = \frac{4 \cdot T c}{W \cdot ((D o) + (D i))}

Next Step Substitute values of Variables

∴

μ collar = \frac{4 \cdot 10000N*mm}{1700N \cdot ((100mm) + (60mm))}

Next Step Convert Units

∴

μ collar = \frac{4 \cdot 10N*m}{1700N \cdot ((0.1m) + (0.06m))}

Next Step Prepare to Evaluate

∴

μ collar = \frac{4 \cdot 10}{1700 \cdot ((0.1) + (0.06))}

Next Step Evaluate

∴

μ collar = 0.147058823529412

LAST Step Rounding Answer

∴

μ collar = 0.1471
