2.4. Final balance

Try these first

1. 1.

   What does Linear Momentum Balance relate to in solid mechanics?

   Hint

   Think about Newton's second law.

2. 2.

   What is an example of body force?

   Hint

   Consider forces that act throughout a volume.

3. 3.

   What principle does Linear Momentum Balance rely on?

   • Principle of Conservation of Mass
   • Newton's Second Law
   • Archimedes' Principle

   Hint

   Think about the fundamental laws of physics.

4. 4.

   True or False: Body forces act only at the surfaces of a body.

   • True
   • False

   Hint

   Consider how forces like gravity work.

5. 5.

   A steel beam is subjected to a force of 2000 N. Its mass is 100 kg. Calculate the acceleration of the beam.

   Hint

   Remember the formula connecting force, mass, and acceleration.

6. 6.

   Describe how you would assess the safety of a suspension bridge using LMB principles.

   Hint

   Think about what forces and torques would need to be calculated.
