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.

In the design in the figure, a force of Fn=1912 N in the vertical plane and a torque of Md=916 Ncm in the clockwise direction of rotation act on a machine element with a diameter of D=200 mm on the shaft resting on the A and B bearings. If the angle of the force with the horizontal is b=49o, how many Newtons is the resultant radial force to be considered in the bearing calculation of the bearing A? 1-) The diameter of the machine element on which the force acts will not be taken into account in the calculation of the bearing forces (ie, it will be assumed that the Fn force acts on the axis of the shaft). 2-) Pi number will be taken as 3.14.
