A set of 10 bolts is to be used to provide a clamping force of 50000 lb between two components of a machine. The load is shared equally among the 4 bolts. Knowing that the grade of the material is SAE Grade 4, if each is to be stressed to 90 %of its proof strength. Then the required tensile stress area is: Select one: 2 A. A, = 0.0714 in %3D 2. B. A, = 0.22 in %3D 2. C. A, = 0.0865 in %3D 2. D. A = 0 0855 i

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.
