Beam Analysis and Journal Activities

Mr. Stewart introduces a beam analysis activity in the CEA class, focusing on design load identification and beam strength analysis. Students will calculate shear and bending-moment, create diagrams, and annotate them with appropriate magnitudes. Instructions are provided for completing the activity in their journals, including sketching Freebody diagrams and using equilibrium equations.

What is the primary role of a structural engineer in beam analysis?

• To calculate the cost of materials

• To analyze and determine the beam strength needed to resist loads

• To manage the construction site

• To design the aesthetic aspects of a building

Why is it important to calculate maximum shear and bending moments?

• To ensure the beam can safely carry the loads

• To determine the color of the beam

• To decide the location of the beam

• To calculate the cost of the beam

What should be included in the journal activity for each beam?

• A list of materials used

• A sketch of the Freebody diagram and calculations of forces

• A description of the construction process

• A timeline of the project

What is the length of the beams discussed in the activity?

• 10 feet

• 20 feet

• 12 feet

• 16 feet

What is the value of the uniform load (aw) on the beams?

• 50 pound foot

• 100 pound foot

• 150 pound foot

• 200 pound foot

What is the value of the concentrated load (P) on the beams?

• 600 pounds

• 300 pounds

• 400 pounds

• 500 pounds

What is the first step in completing the journal activity?

• Write a summary of the video

• List the tools needed for the activity

• Cut out and paste the beam diagram into the journal

• Calculate the cost of materials

What should be done after sketching the Freebody diagram?

• Write a report

• Paint the beam

• Submit the journal

• Calculate the reaction forces and shear using equilibrium equations

What is the final task in the journal activity?

• Submit the journal for grading

• Write a reflection on the activity

• Annotate the diagrams with appropriate shear and moment magnitudes

• Present the findings to the class
