Problem 2. Start with a base/fixed link that is 65 mm long. Create a four-bar linkage from the fixed link, such that the linkage fulfills the Grashof requirements (full revolution of the shortest link). Draw it to scale in a typical configuration and show the lengths of the links. Label the links as "Fixed Link," "Input Link," "Output Link," "Coupler Link." Show the math to prove that it is a Grashof linkage. Comment on whether it is a crank rocker, double crank, or double rocker.
