Try these first

1. 1.

   What is a bending moment?

   Hint

   Think about how beams bend under weight.

2. 2.

   Define equilibrium in your own words.

   Hint

   What happens when forces cancel each other out?

3. 3.

   What defines the state of equilibrium?

   • Balanced forces
   • Moving forces
   • No forces acting

   Hint

   Think about what would happen if forces are not balanced.

4. 4.

   True or False: A bending moment only exists in moving structures.

   • True
   • False

   Hint

   Remember that structures can be stationary yet experience forces.

5. 5.

   Given a simply supported beam with several loads, calculate the maximum bending moment and identify critical sections.

   Hint

   Draw a free body diagram to assist in visualization.

6. 6.

   Design a cantilever beam that can withstand a specified point load and uniform load while managing bending moments effectively.

   Hint

   Consider factors like material strength and safety margins.
