Combined Loading

Any functioning component, such as machine parts, structural members, pressure vessels, and so on, are all under the influence of more than one force. When anybody is under the influence of more than one force such as shear forces, bending moments, axial forces, torsion, and so on, then such body is said to be under combined loading. A very practical example of combined loading is the crankshaft of an internal combustion engine (IC engine). The crankshaft of the IC engine is under high rpm, which is caused due to the torsional forces. Due to the presence of piston, counterbalances, and internal imbalances, the crankshaft experiences lateral forces and due to the rise in temperature, the crankshaft undergoes thermal expansion, which pulls the crankshaft along the axial direction and lateral direction. The presence of unbalanced loads along the periphery of the crankshaft also induces a bending moment.

Question

After recording the applied twisting moment and resulted angle, fill the following
table
MT

T.
MPa
(degree)
(rad.)
Now, the twisting moment-twisting angle and shear stress-shear strain curves can
be plotted, then determine maximum shear stress, shear stress at proportional limit
and modulus of rigidity.

Próblem 1-19. A mild steel hollow shaft of 100 mm external di- ameter and 40 mm internal diameter is subjected to a twisting moment of 6 kN.m and a bending moment of 4 kN.m. Find the direct stress, which acting alone, would produce the same (a) maximum elastic strain energy, (b) maximum elastic shear strain energy, as that produced by the principal stresses acting together. Poisson's ratio is 0-30.
x Question: The diameter of shaft used in the below design is 90 mm. Identical pulleys are used in the design with a radius of 160 mm. The forces acting on the system are defined as follow: F₁ = 1P kN; F₂ = 8P kN; F3 = 2P kN; F₁ = 6P kN; F5 = 4P kN; F = 7P kN. Employing the maximum shear stress theory, calculate the maximum permissible P for a safe design experience.
