Percent Anti Squat Solution

Follow our step by step solution on how to calculate Percent Anti Squat?

FIRST Step Consider the formula

%AS = (\frac{\tan (ΦR)}{\frac{h}{b ind}}) \cdot 100

Next Step Substitute values of Variables

∴

%AS = (\frac{\tan (18.43°)}{\frac{10000mm}{1350mm}}) \cdot 100

Next Step Convert Units

∴

%AS = (\frac{\tan (0.3217rad)}{\frac{10m}{1.35m}}) \cdot 100

Next Step Prepare to Evaluate

∴

%AS = (\frac{\tan (0.3217)}{\frac{10}{1.35}}) \cdot 100

Next Step Evaluate

∴

%AS = 4.49870443848518

LAST Step Rounding Answer

∴

%AS = 4.4987
