Detailed Solution
Download Solution PDFदिया गया है: PP = 30 kN, QP = 45 kN और k = 3.
\({\rm{L_{10}}} = {\left( {\frac{{\rm{C}}}{{\rm{P}}}} \right)^{\rm{k}}} \times {10^6}{\rm\;{revolution}}\)
∵बेयरिंग की गतिक भार धारिता समान है अर्थात CP = CQ.
\(\left ( \frac{L_{10P}}{L_{10Q}} \right )=\left ( \frac{P_Q}{P_P} \right )^3\Rightarrow\left ( \frac{45}{30} \right )^3=\frac{27}{8}\)
