In the fifth and last part of our series, we will look at the isosceles linkages: isosceles double-crank, isosceles crank-rocker and the rhombus-crank.
In this third part of our series, we will discuss the double-rocker. In this type of four-bar linkage, both grounded links are not able to revolve fully.
We continue our video series with the double-crank. In contrast to the crank-rocker, in a double-crank mechanism both grounded links can revolve fully, which is where its name comes from.
The first part of our video series features the crank-rocker. In a crank-rocker mechanism, one grounded link is able to revolve fully while the other one is not.
