Concept explainers
The flywheel OD on the elliptical machine analyzed in the case study for this chapter has a constant angular velocity of 5.5 rad/s clockwise. Note that bar ABD is one solid rigid body, Connected to bar EBF at point B. The r and y locations of each point, expressed in inches, are provided in the table, where the reference origin is at point O . Note that both point O and H are fixed points, and A is a roller that can move in the horizontal plane. At the instant when
