1) Write a MATLAB function that will use load ratings for 6300 series ball bearings and the AFBMA equivalent load formula to compute L10 bearing life. Attach hardcopy of your main program and function.
The input to your function should be a vector [ BearingNumber Fr Fa ]. BearingNumber should be a value from 6300 through 6320. Variables Fr and Fa should be radial and axial force on the bearing with units lbf. Use MATLAB "interp1" with linear interpolation and extrapolation to determine load factors X and Y with V = 1. Use code provided on the next page for tables.n
2) To validate your function, provide plots of log(L10) for each bearing number as shown below. Validate two cases: a) Fr = 1449 lbf, Fa = 0 and b) Fr = 1449 lbf, Fa = 1310 lbf. Attach hardcopy of your validation plot.
3) Use your function to select the smallest bearing that can provide minimum L10 life of 100x106 revolutions with Fr = 2000 lbf and Fa = 1500 lbf applied and the inner race rotating. Specify expected L10 life, bearing bore, outside diameter and axial width with units mm.
