Length of Open Belt Drive Solution

Follow our step by step solution on how to calculate Length of Open Belt Drive?

FIRST Step Consider the formula
L'b=π(r2+r1)+2x+(r1-r2)2x
Next Step Substitute values of Variables
L'b=π(6m+10m)+230.55m+(10m-6m)230.55m
Next Step Substitute values of Constants
L'b=3.1416(6m+10m)+230.55m+(10m-6m)230.55m
Next Step Prepare to Evaluate
L'b=3.1416(6+10)+230.55+(10-6)230.55
Next Step Evaluate
L'b=111.889214044998m
LAST Step Rounding Answer
L'b=111.8892m
