What is the role of elastic parts, such as springs, In the context of mechanisms?

• They are considered rigid links in mechanisms

• They are essential for kinematic analysis

• They have no effect on the kinematics of the mechanism

• They replace the frame of reference in kinematics

Why is one part typically designated as the frame in a mechanism?

• To ensure it exhibits the most motion.

• To indicate it is the primary source of power.

• To provide a stationary reference for the motion of other parts.

• To emphasize its importance in transmitting forces.

What is a complex link?

• A link that has one joint.

• A link that contains more than two joints.

• A flexible link with two joints.

• A rigid body with no joints.

What does a point of interest on a link refer to?

• The point where the link is strongest.

• The center of the link.

• The point where two links intersect.

• A point on a link where the motion is of special interest.
