The limiting wear load of spur gear is proportional to (where \[{{E}_{p}}\,\,=\] Young's modulus of union material; \[{{E}_{g}}\,\,=\] Young's modulus of gear material:

A) \[{{({{E}_{p}}+{{E}_{g}})}^{-1}}\]              

B) \[\left( \frac{{{E}_{p}}+{{E}_{s}}}{{{E}_{p}}{{E}_{s}}} \right)\]

C) \[\left( 1+\frac{{{E}_{p}}}{{{E}_{s}}} \right)\]              

D) \[\left( 1+\frac{{{E}_{g}}}{{{E}_{B}}} \right)\]
