Forces of magnitude F; =7 kN in the +y direction and F 2 =13 kN in Question 2) the -z direction are acting on the arm from point B in the figure . From the point C, a moment of magnitude M=5 kN.m acts in the +y direction . The lengths of the arm are also given as L =0.2 m and L2 =0.3 m . The radius r in the aa section taken over the arm is r=0.013 m and it is desired to determine the stress state at point A. The shear modulus of the sleeve material is G=75 Gpa . According to this; Question 2-C) Find the normal stress caused by the normal force at point A. ( Write your result in MPa .) Response: Question 2-D) at the point A due to the bending moment (F ; consisting of force) normal stress occurring to find. ( Write your result in MPa .)

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.
