3.1. Uniform Velocity (UV)

Try these first

1. 1.

   What does uniform velocity mean in cam design?

   Hint

   Think about speed remaining unchanged.

2. 2.

   What happens to acceleration in uniform velocity motion?

   Hint

   No change in velocity leads to this result.

3. 3.

   What is the definition of uniform velocity?

   • A constant speed of the follower
   • Speed increasing over time
   • Speed decreasing over time

   Hint

   Focus on the meaning of 'uniform'.

4. 4.

   True or False: Jerk in motion can lead to vibrations in machines.

   • True
   • False

   Hint

   Remember what jerk affects in a mechanical context.

5. 5.

   A cam profile is designed to operate at uniform velocity, but vibrations have been reported. What might be the cause and how would you resolve it?

   Hint

   Think about how jerk contributes to potential mechanical stress.

6. 6.

   Design a motion diagram for a cam running at uniform velocity, indicating points where jerk may occur. Explain your reasoning.

   Hint

   Visualize the movements and how they change relative to one another.
