1.
This question relates to stresses due to combined loading.
A shaft subjected to combined torsion and axial thrust is designed to resist a shear stress and
a compressive stress as shown in Figure Q1. Using the information provided in Table Q1:
Figure Q1
Txy
90 mpa
ox
130 mpa
a) Determine the principal stresses and show them on a sketch of a properly oriented element.
b) Determine the maximum shear stresses and associated normal stresses and show them
on a sketch of a properly oriented element.
c) Calculate the safety factors according to the three theories (Rankine, Tresca, and Von-
Mises). Take the yield strength of the material as, Oyield = 250 MPa.
d) Sketch the Mohr's circle for the stressed component location and indicate the stress
states, principal stresses, and maximum shear stress.
