Question 5The nose wheel assembly of an aircraft shown in Figure 3 has axle shaft whichis 150 mm long. The shaft has a diameter Di of 30 mm for the section AB, whichis connected to the arm. Section BC of the shaft that is connected to the wheelhas diameter D2 of 25 mm. Sections AB and BC of the shaft have massmoments of inertia of 80 kgm2 and 60 kgm?, respectively. If the modulus ofrigidity of the shaft material is 80 GN/m, calculate the natural frequency oftorsional vibration of the system.ArmD,D,100 mmAxle shaftFigure 3: Aircraft wheel assembly

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.

Solve fast please
A motor is mounted on a platform that is observed to vibrate excessively at an operating speed of 6000 rpm, producing a 250 N force. Design a vibration absorber (undamped) to add to the platform such that the displacement of the motor becomes zeo. Note that in this case, the absorber mass will only be allowed to move 2 mm because of geometric and size constraints.
