6. Equations of Motion for Four-Bar Linkage

Try these first

1. 1.

   What does angular acceleration represent in motion analysis?

   Hint

   Consider the change in the position of a link.

2. 2.

   What is the equation for inertial torque?

   Hint

   Recall how mass and angular acceleration relate.

3. 3.

   What does angular acceleration represent?

   • Rate of change of position
   • Rate of change of velocity
   • Rate of change of angle

   Hint

   Think about what part of motion involves angles.

4. 4.

   True or False: The equation for inertial torque is T = m * a.

   • True
   • False

   Hint

   Recall how mass relates to torque and acceleration.

5. 5.

   A four-bar linkage has a mass of 2 kg and a radius of gyration of 0.5 m. If the angular acceleration is 6 rad/s², calculate the inertial torque acting on one of the links.

   Hint

   Recall how moment of inertia relates to mass and distribution.

6. 6.

   Describe how you would conduct a dynamic analysis of a four-bar linkage with varying speeds. Include kinematic analysis results.

   Hint

   Frame your approach methodically, ensuring each required aspect is covered.
