Question 1.
What is the definition of an Instantaneous Center (IC)?
Show hintHide hint
Focus on the purpose of the IC in simplifying motion analysis.
Question 2.
State Kennedy's theorem in your own words.
Show hintHide hint
Think about how the links relate to each other.
3Question 3.
What does the Instantaneous Center represent?
- A point of rest
- A point of rotational motion
- A point of linear motion
Show hintHide hint
Think about the definition of IC.
4Question 4.
True or False: Kennedy's theorem is applicable only to linear motion.
- True
- False
Show hintHide hint
Recall the applications of Kennedy's theorem.
Question 5.
Given a three-link planar mechanism, find all the ICs and calculate the velocity of one point on the system when the angular velocity is 2 rad/s.
Show hintHide hint
Draw sketches for each link connection and clearly label the distances.
Question 6.
Consider a system where the angular velocity of one link is altered. How would this change affect the velocities of other points, identified through IC? Analyze and provide a detailed explanation.
Show hintHide hint
Focus on how changes in one link’s motion influence the others through the IC.
