The shaft is supported by a smooth thrust bearing at B and a journal bearing at C. Determine the resultant internal loadings acting on the cross section at E.
The free-body diagram is shown below.
Solve for Cy by taking moment at point B
Pass a cutting plane at section E. The free-body diagram of the resulting figure is shown
Take the sum of forces in the x-direction, and equate to zero
Take the sum of forces in the y-direction and equate to zero
Take the sum of moments at point E
The negative signs indicates that act in the opposite sense to that shown on the free-body diagram.
