Problem $11\mathrm{.}035-$ Selection of a bearing for a shaft design

The figure is a schematic drawing of a countershaft that supports two V$-$belt pulleys. Then countershaft runs at $1200$ revimin and the bearings are to have a life of $55$ kh at a combined rellability of $0\mathrm{.}970,$ assuming distribution data from manufacturer $2$ in Table $11-6.$ The belt tension on the loose side of pulley A is $15$ percent of the tension on the tight side. Select deep$-$groove bearings from Table $11-2$ for use at $O$ and $E,$ using an application factor of unity.

Problem $11\mathrm{.}035.$a $-$ Determination of resultant bearing reactions

What are the values of the resultant bearing reactions at points $O$ and $E$ on the shaft?

The resultant at point $O$ is N $.$

The resultant at point $E$ is $N.$
