2.2. Velocity

Try these first

1. 1.

   Define velocity in your own words.

   Hint

   Think about the relationship between distance and time.

2. 2.

   What is the formula for linear acceleration?

   Hint

   Consider how tangential acceleration connects to angular acceleration.

3. 3.

   What does the velocity formula v = ω × r represent?

   • Linear acceleration
   • Linear velocity
   • Angular displacement

   Hint

   Focus on the connection between radius and rotation.

4. 4.

   True or False: The tangential acceleration is directly related to the angular acceleration.

   • True
   • False

   Hint

   Think about the relationship between angular and linear concepts.

5. 5.

   How would you analyze a four-bar linkage mechanism using loop closure equations for given angles?

   Hint

   Focus on the relationships between the four links to form the equations.

6. 6.

   Calculate the Coriolis component of acceleration for a sliding point given an angular velocity of 0.3 rad/s and a relative velocity of 5 m/s.

   Hint

   Consider how the angular velocity affects the component during different sliding scenarios.
