Problem 2: Consider the two gears mounted on the shaft, as shown. Distances are L1 = 100 mm, L2 = 250 mm, and L3 = 175 mm. Diameter of shaft ABis 15 mm, diameter of shaft BC is 20 mm, and diameter of shaft CD is 17.5 mm. Young's modulus for each portion is 200 GPa.Determine the displacement of point D with reference to point A. Also, determine the displacement of point A relative to C.b.Determine the axial strain at any point in shaft segments AB, BC and CD, respectively.If Poisson's ratio for the material of the shafts is v = 0.2, determine the lateral strain in each of the shaft segments.Based on your answers to part (a), do the gears move towards each other, or do they separate from each other? Note that in real gearboxes,movement of gears towards or away from each other is prevented by using thrust bearings.10 kN4 kN5 kN7 kN4 kNNY 0I17.
