Angle of inclination of thread Solution

Follow our step by step solution on how to calculate Angle of inclination of thread?

FIRST Step Consider the formula

θ t = a \tan (\frac{P s}{π \cdot d m})

Next Step Substitute values of Variables

∴

θ t = a \tan (\frac{12.5m}{π \cdot 1.7m})

Next Step Substitute values of Constants

∴

θ t = a \tan (\frac{12.5m}{3.1416 \cdot 1.7m})

Next Step Prepare to Evaluate

∴

θ t = a \tan (\frac{12.5}{3.1416 \cdot 1.7})

Next Step Evaluate

∴

θ t = 1.16701587180889rad

Next Step Convert to Output's Unit

∴

θ t = 66.8650840794423°

LAST Step Rounding Answer

∴

θ t = 66.8651°
