$*1-12.$ Determine the resultant internal loadings on the

cross section at point $D.$ Assume point $D$ is just to the left

of the $60-kN$ force. Assume the support reactions at A and

$B$ are vertical.

Probs. $1-11/12,-5.$ The shaft is supported by a smooth thrust bearing

at $B$ and a smooth journal bearing at $A.$ Determine the

resultant internal loadings acting on the cross section at $C.$
