3. Instantaneous Center (IC) Method for Velocity Analysis

Try these first

1. 1.

   What is the Instantaneous Center?

   Hint

   Think about the rotation of a rigid body.

2. 2.

   How do you calculate velocity using the IC method?

   Hint

   Recall the relationship between angular velocity and the radius.

3. 3.

   What does IC stand for in the context of mechanisms?

   • Internal Circle
   • Instantaneous Center
   • Instantaneous Circle

   Hint

   Focus on what it represents in motion.

4. 4.

   Is Kennedy's theorem applicable to any planar mechanism?

   • True
   • False

   Hint

   Think about the nature of planar linkages.

5. 5.

   In a complex slider-crank mechanism where the crank rotates at 20 rad/s and the connecting rod is 1.5 m. What is the velocity of the slider when the IC is 0.75 m from it?

   Hint

   Utilize the formula once you've identified the distances.

6. 6.

   A robotic arm consists of multiple linkages. If the total angular velocity is 25 rad/s and the IC for the last link is found at 0.5 m, calculate the velocity of this link.

   Hint

   Always remember to apply the correct relationship between distance and angular velocity.
