(b) How many DOFs does a helical joint have? (c) True or false? By changing the ground link, we can change a non-Grashof mechanism to a Grashof mechanism (d) What is the importance of transmission angle? (e) Intermittent motion is a sequence of motions and dwells. Define the term "dwell." (f) What are the advantages of using a fourbar mechanism instead of a cam? (g) What is a cusp on a coupler curve? Draw a coupler curve with a cusp. (h) Why a fourbar mechanism cannot have a time ratio of 1:3? (i) Define the term "Mobility" of a mechanism in the physical context of ME154. (1) True or false? Complete shrinkage of a ternary link will change the DOF. 2
