The cantilevered bar in the figure is made from a ductile material and is statically loaded
with F,, = 200 lbf and Fx = F₂ = 0. Analyze the stress situation in rod AB by obtaining
the following information. Note that the stress concentration factors are neglected in the
following questions (Kt and Kts=1).
(a) Determine the precise location of the critical stress element.
(b) Sketch the critical stress element and determine magnitudes and direction for all
stresses acting on it. (Transverse shear may only be neglected if you can justify this
decision.)
(c) For the critical stress element, determine the principal stresses and maximum shear
stress.

- A rotating shaft is made of 42 mm by 4 mm thick cold-drawn round steel tubing and has a 6 mm diameter hole drilled transversely through it. The shaft is subjected to a pulsating torque fluctuating from 20 to 160 Nm and a completely reversed bending moment of 200 Nm. The steel tubing has a minimum strength of Sut = 410 MPa (60 ksi). The static stress-concentration factor for the hole is 2.4 for bending and 1.9 for torsion. The maximum operating temperature is 400˚C and a reliability of 99.9% is to be assumed.
