Question

For a ball bearing, the fatigue life in millions of revolutions is given by \(L=\frac{C}{P}^n\), where P is the constant applied load and C is the basic dynamic load rating. Which one of the following statements is TRUE?

• A. n = 3, assuming that the inner racing is fixed and outer racing is revolving
• B. n = \(\frac{1}{3}\), assuming that the inner racing is fixed and outer racing is revolving
• C. n = 3, assuming that the outer racing is fixed and inner racing is revolving
• D. n = \(\frac{1}{3}\), assuming that the outer racing is fixed and inner racing is revolving

Answer 1

The Correct Option is C

The correct option is (C): n = 3, assuming that the outer racing is fixed and inner racing is revolving
