3. Classification of Mechanisms

Try these first

1. 1.

   Name one example of a mechanism that generates motion.

   Hint

   Think about types of machines you use daily.

2. 2.

   What type of constraint does a fully constrained mechanism have?

   Hint

   Consider how well-defined the motion is.

3. 3.

   What type of mechanism would primarily be used for force transmission?

   • Gears
   • Levers
   • Linkages

   Hint

   Think about what parts of a machine are meant to pass on power.

4. 4.

   True or False: An unconstrained mechanism has fixed motion.

   • True
   • False

   Hint

   Consider what 'unconstrained' means in this context.

5. 5.

   Design a simple introductory mechanism that uses the Four-Bar design to convert rotary motion into linear motion. Describe its application.

   Hint

   Consider practical uses in machinery.

6. 6.

   Analyze the differences in efficiency between a fully constrained mechanism and one that is partially constrained when operating under load.

   Hint

   Think about stability versus flexibility in mechanical systems.
