1.4. Final balance

Try these first

1. 1.

   What does AMB stand for?

   Hint

   Think about the main topic of the section.

2. 2.

   Define body force.

   Hint

   Consider forces like gravity.

3. 3.

   What does the term 'traction' refer to in mechanics?

   • Internal force
   • External force
   • Frictional force

   Hint

   Think about forces applied from outside.

4. 4.

   True or False: The AMB equation is only valid when external forces are applied.

   • True
   • False

   Hint

   Consider what the equation represents.

5. 5.

   A hollow cylindrical shell is subjected to an external force. Derive the AMB equation including both body and traction forces. Discuss all significant assumptions made.

   Hint

   Use symmetry and properties of torques in your derivation.

6. 6.

   Demonstrate how the AMB equation can predict the movement of a pendulum subjected to varying external torques. Describe how forces affect its angular momentum.

   Hint

   Remember to include the importance of gravitational body force in pendulum motion.
