Determine the followings:

From problem $1,$ use the FBD of the forces acting on the shaft to find the resulting reactions at support locations $O$ and $B.$

If identical bearings are to be used at both locations $(O$&$B),$ which bearing location is critical and what is the radial load $F_D$ at this location?

What is the desired life $L_D$ and bearing reliability $R_D?$

Find the catalog load rating $C_{10}$ of the maximum radial load.

Choose $02-$series deep$-$groove ball bearings from Table $11-2.$
