A mass less spring having a spring content k=185 N/m, is inside a horizontal barrel. It's left end is rigidly fixed at position z= 0.0 cm, and it's right end is at X=L, where L=19.7 cm. The spring is then squeezed so that the right end of the spring is at the X=s, where S=13 cm. A ball of mass 50g is put in front of the spring and the spring is released. Calculate

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.
