Problem 7.4-8 The rotor shaft of a helicopter (see
figure part a) drives the rotor blades that provide
the lifting force and is subjected to a combination
of torsion and axial loading (see figure part b).
It is known that normal stress ơ, = 68 MPa
and shear stress Try = -100 MPa. Using Mohr's
circle, determine the following.
68 MPа
(a) The stresses acting on an element oriented
at a counterclockwise angle 0
the x axis.
= 22.5° from
100 MPа
(b) Find the maximum tensile stress, maximum
compressive stress, and maximum shear
stress in the shaft.
(b)
Show all results on sketches of properly oriented elements.
