Tolerance Unit Solution

Follow our step by step solution on how to calculate Tolerance Unit?

FIRST Step Consider the formula
i=0.45(CD)13+0.001CD
Next Step Substitute values of Variables
i=0.45(27mm)13+0.00127mm
Next Step Convert Units
i=0.45(0.027m)13+0.0010.027m
Next Step Prepare to Evaluate
i=0.45(0.027)13+0.0010.027
Next Step Evaluate
i=0.135027
LAST Step Rounding Answer
i=0.135
