Four bar linkage 8a

A special case of the 4-bar linkage. Input: pink crank Output: green crank. The unusualness: a working cycle of the mechanism corresponds 2 revolutions of the input. Output oscillating angle is larger than 180 deg., a thing that is hard to get by using an ordinary 4-bar linkage. It happens because: 1. The sum of the lengths of the two adjacent links is equal to the sum of the lengths of the other two links. A + B = C + D A: length of pink crank (=10) B: length of yellow conrod (=40) C: length of green cran
