Length of effort arm of lever given bending moment Solution

Follow our step by step solution on how to calculate Length of effort arm of lever given bending moment?

FIRST Step Consider the formula
l1=(d1)+(MbP)
Next Step Substitute values of Variables
∴ l1=(12.3913mm)+(275404N*mm310N)
Next Step Convert Units
∴ l1=(0.0124m)+(275.404N*m310N)
Next Step Prepare to Evaluate
∴ l1=(0.0124)+(275.404310)
Next Step Evaluate
∴l1=0.9007913m
LAST Step Convert to Output's Unit
∴l1=900.7913mm
