A high carbon steel shaft is used in an engine and subjected to
different loads. In order to analyse the stress in the shaft,
consider a rectangular element within the material. This element is
subjected to compressive stress of 135 MPa and shear stress of
166MPa in the vertical direction. The compressive stress in the
horizontal direction is 176MPa with a shear stress of
115MPa.
d. What will be the difference in the analysis above if there is
an additional torsional load (T) and bending moment (M).
e. Show how you can use any theory of failure to design this
shaft.
f. What are the challenges of applying the theories of failure in
actual engineering practice and as a design engineer, how would you
deal with these challenges.
a. Sketch the state of stress on this element.
b. Determine the maximum and minimum normal and shear stresses and
their plane of orientation.
c. If the yield strength of the material is 350MPa, Poison’s ratio
is 0.32, and factor of safety is 5, determine the diameter of the
shaft to avoid failure.

For steel member is subjected to cyclic loads,
The experimental results indicated failure at a number of cycles
of 52 when the maximum stress is 1071 MPa. Also, failure at a
number of cycles of 380,000 when the applied maximum stress is 506
MPA.

A shaft cycles such that each bearing undergoes the radial loads
of 30% of the time at 20kN, 50% of the time at 25kN, and 20% of the
time at 30kN. If the design life of a bearing is to be at least 5e6
revolutions, select the smallest 03 series cylindrical roller
bearing that will accomplish this.

A plain bearing used in industrial application operates
at high speed under very high loads. All elements of this plain
bearing (bearing and journal) are made of 080M40 steel. In order to
prolong the life of the mattress, you are asked to replace one
element of the plain bearing with the materials in the list below
(journal or bearing will replace only one). Why which material
would you choose?
Rice
Bullet
Teflon

A solid shaft is designed to twist no
more than an angle of 2º when subjected to a torque of 800 Nm. The
shaft is 1 m long and made from a material that has a shear
modulus, G = 70 GN/m2. Select an appropriate minimal
diameter for the design specifications if
Solid shaft was used.
Hollow shaft of wall thickness 5mm was used.
If the shaft is to rotate at 2000 rpm, determine the maximum
