AFigure 1
BFigure 2
CFigure 5
DFigure 6
AI Explanation
The correct answer is B) Figure 2. In the illustration MO-0025, the crosshead experiences the greatest side thrust in Figure 2. This is because the connecting rod is offset from the centerline of the cylinder, creating a side thrust on the crosshead as the piston travels. The other figures do not show this offset arrangement, and therefore the crosshead would not experience as much side thrust. The other answer choices are incorrect because: A) Figure 1 does not show the offset connecting rod arrangement. C) Figure 5 does not show the offset connecting rod arrangement. D) Figure 6 does not show the offset connecting rod arrangement.
