A device contains two bearings is to operate at 300 rev/min, 8 hours per day, 5 days per week for 5 years with a reliability of 0.99. The design load is (2000+ N) Newton and an application factor of 1.2 is appropriate. Find the catalog rating C₁0 a) For ball bearings b) For roller bearings The Weibull parameters are xo = 0.02, (0-xo) = 4.439, and b = 1.483. Use SI units. Take the relations as C10= af Fo Notes: XD xo+ (0-xo) (1 - R₂)¹/b 1/a and XD = Lond60 LR Where the subscripts D: desired R: rating f: factor N is Your Rank Number in the Class List. - Take at least 3 digits after the decimal point. - Specify the units. - Show your all equations on the page(s). You can use your own handwriting, Word Equation or pasting of your solution picture.
