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.

Question

A solid aluminum 2014-T6 shaft with a
diameter of 80 mm is inserted
concentrically inside a steel tube.
Determine the inner diameter (in mm) of
the tube so that there is no contact
preassure between shaft and tube, even
though the cooper supports an axial
compression force of 400 kN
