2.1. Displacement

Try these first

1. 1.

   Define displacement in your own words.

   Hint

   Think about starting and ending points.

2. 2.

   What is the formula for velocity?

   Hint

   Remember the relationship between distance and time.

3. 3.

   What is displacement?

   • The distance from origin
   • Position relative to a reference
   • Speed of an object

   Hint

   Think about starting and finishing locations.

4. 4.

   True or False: Acceleration is the rate of change of displacement.

   • True
   • False

   Hint

   Remember what acceleration actually measures.

5. 5.

   Calculate the angular velocity and the linear velocity of two points on a rotating disk of radius 1 meter if the disk is spinning at 2 radians per second.

   Hint

   Use the relationship between linear and angular velocities.

6. 6.

   Analyze a four-bar linkage system with specified lengths and angular velocities, and determine the position of the output link.

   Hint

   Break it down into segments — use angles from known input links.
