Question: A rotating shaft which is supported at point A and D by rolling contact bearings is shown in following figure. A force of Fext is carried out by shaft; the direction and magnitude of this force is not changing during operation. Calculate life of the shaft based on the values given in Table $2.$

NOTES:

Use $dl=d5.$

Table $1$ shows units of paraemeters given in Table $2.$

Use values given to make calculations for you in Table $2.$

Do not forget to give page numbers for your report.

You can prepare your report by hand or Excel.

You can assume any parameter if it is impossible to find, calculate or read it from any figure$-$table.

Do not make any unnecessary assumptions.
