The shaft is supported at its ends by two bearings A and B and is subjected to the forces applied to the pulleys fixed to the shaft. Determine the resultant internal loadings acting on the cross section located at point C. The 300-N forces act in the –z direction and the 500-N forces act in the +x direction. The journal bearings at A and B exert only x and z components of force on the shaft.
