Answer :
Final answer:
Grashof's Criterion helps identify the category of a four-bar mechanism, with this specific mechanism categorized as crank-rocker. The correct option is b.
Explanation:
Grashof's Criterion is used to determine the category of a four-bar mechanism. By analyzing the links and their relative lengths, we can identify the motion characteristics. In this case, based on the criteria, the mechanism falls under the category of crank-rocker (b).
However, the information provided does not include the lengths of the links, which are essential to apply Grashof's Criterion. This criterion states that for a planar four-bar linkage, if the sum of the shortest link and the longest link is less than or equal to the sum of the other two links, and the shortest link can rotate fully with respect to a neighboring link, the linkage is a Grashof mechanism.
A Grashof linkage will have at least one rotating link, which makes a complete 360° revolution. The correct option is b.
