Question 1.
What is the Instantaneous Center?
Show hintHide hint
Think about the rotation of a rigid body.
Question 2.
How do you calculate velocity using the IC method?
Show hintHide hint
Recall the relationship between angular velocity and the radius.
3Question 3.
What does IC stand for in the context of mechanisms?
- Internal Circle
- Instantaneous Center
- Instantaneous Circle
Show hintHide hint
Focus on what it represents in motion.
4Question 4.
Is Kennedy's theorem applicable to any planar mechanism?
- True
- False
Show hintHide hint
Think about the nature of planar linkages.
Question 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?
Show hintHide hint
Utilize the formula once you've identified the distances.
Question 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.
Show hintHide hint
Always remember to apply the correct relationship between distance and angular velocity.
