Consider the double-rocker mechanism in Figure P2.6.
a. What should the relationship between the links dimensions be in order for the connecting link to make a complete rotation while the arms are rocking?
b. Assume 2a = 1 cm, h = 0.5 cm, 2d = 10 cm, and that the arms have equal length 7 cm. What is the angle of arm 1 rocking?
