Final answer:
Cams can be classified by the type of follower, cam surface, motion program, and cam rotation. This classification determines how the cam transfers motion to the follower. Synovial joints in the human body are classified differently, based on structure and function.
Step-by-step explanation:
Ways to classify cams can include the type of follower, the type of cam surface, the type of motion program, and the type of cam rotation. These classifications allow for the design of cams to be tailored to specific mechanical requirements, ensuring that the movements of followers accurately translate into the desired output. Unlike cams, synovial joints in the human body are classified by their structure and resulting function, such as pivot, hi nge, saddle, plane, condyloid, and ball-and-socket joints, each allowing different types of movement like gliding, angular, rotational, or special movements.
