2. Types of Joints (Kinematic Pairs)

Try these first

1. 1.

   What type of joint allows rotation about an axis?

   Hint

   Think about door movements.

2. 2.

   Identify a joint that allows sliding along a surface.

   Hint

   Consider how a drawer operates.

3. 3.

   What type of joint allows sliding motion?

   • Screw Joint
   • Prismatic Joint
   • Revolute Joint

   Hint

   Think about how a drawer opens.

4. 4.

   True or False: Higher pairs are characterized by surface contact.

   • True
   • False

   Hint

   Recall the definitions of both pairs.

5. 5.

   If a machine uses both revolute and prismatic joints, describe how you would analyze the motion of such a system.

   Hint

   Consider how both types of movement contributes to the overall function.

6. 6.

   Design a simple mechanical system that utilizes at least two different types of joints and describe their roles.

   Hint

   Think about how different tasks can require different movements.
