Question 1.
Define a cantilever beam.
Show hintHide hint
Think about where the beam is supported.
Question 2.
What does shear force cause?
Show hintHide hint
Relate this to how beams respond to loads.
3Question 3.
What is the primary advantage of Timoshenko Beam Theory over Euler-Bernoulli Theory?
- It considers only bending.
- It includes shear deformation.
- It's simpler to use.
Show hintHide hint
Think about when shear becomes significant.
4Question 4.
True or False: A cantilever beam can loosely be defined as a beam that is supported on both ends.
- True
- False
Show hintHide hint
Consider the definition of a cantilever.
Question 5.
A cantilever beam of length L is loaded with a force P at the free end. Using Timoshenko Beam Theory, derive the deflection equation.
Show hintHide hint
Don't forget to consider both moments and shear at the fixed end.
Question 6.
Compare the deflection of a cantilever beam from both TBT and EBT when subjected to the same load, and determine the conditions under which each theory applies.
Show hintHide hint
Use a diagram to illustrate how loads affect C and D in the two theories.
