11.4. Longitudinal and Cross Section of a Cantilever Beam

Try these first

1. 1.

   What is a cantilever beam?

   Hint

   Think about where the support is located.

2. 2.

   Name one key aspect to include when drawing a longitudinal section.

   Hint

   What does the section need to show?

3. 3.

   What distinguishes a cantilever beam from other types of beams?

   • Supported at both ends
   • Free at one end
   • Has a uniform section

   Hint

   Think about the support points.

4. 4.

   True or False: Reinforcement helps prevent beams from bending.

   • True
   • False

   Hint

   Consider the role of steel in concrete.

5. 5.

   Design a cantilever beam to hold a load of 5 kN extending 2 m from the support. Specify the dimensions and reinforcement details.

   Hint

   Focus on safety factors and industry standards.

6. 6.

   Analyze the failure mode of an under-reinforced cantilever beam subjected to a sudden load. Describe the implications.

   Hint

   Consider what happens when loads exceed designed limits.
