Design of Shafts and Shaft Components

The shaft is basically defined as the machine element that rotates, is in circular cross-section, it is majorly used to transfer the power from one part of the system to another, or from a power generating machine to a power absorbing machine. The shaft is supported on bearings and is rotated with the help of a set of gears or pulleys that are used for the power transmission. Bending moment, torsion, and an axial force act upon the shaft. Designing of shaft primarily involves determining stresses at a critical point in the shaft that is arising due to loading.

Problem 5: Draw the shear and moment diagrams for the shaft in the figure below. The support A is a thrust bearing and the support at B is a journal bearing. Note: You can ignore the cross-sectional changes at the load application points. The shear and moment diagrams are just for the shaft. Also, note that a thrust bearing acts similarly to a pin and a journal bearing similar to a roller. 3 kN 2 kN 2 kN - 2m -- 2m -- 2m-2m-
