2.1. Example 1

Try these first

1. 1.

   What is a bending moment?

   Hint

   Think about how forces affect a beam.

2. 2.

   Identify the boundary condition at a clamped end of a beam.

   Hint

   Recall the terms from our lectures.

3. 3.

   What is the main assumption of the Euler-Bernoulli Beam Theory?

   • Beam cross-section is always cylindrical
   • Cross-sections remain planar and normal after deformation
   • Axial displacement is significant

   Hint

   Remember how we discussed assumptions in the context of EBT.

4. 4.

   A simply supported beam has a zero reactive moment. True or False?

   • True
   • False

   Hint

   Consider what types of supports create moments.

5. 5.

   A beam 10m long is clamped at one end and has a point load of 250N at the free end. Calculate the deflection of the beam using EBT.

   Hint

   Recall the process to use EBT formulas effectively.

6. 6.

   Analyze a beam of length L subjected to a varying distributed load from 0 to P. Describe how the bending moment would change along the beam.

   Hint

   Recall how distributed forces translate into bending moments.
