Question 1.
Define shear force.
Show hintHide hint
Think about what happens when forces try to slide parts of the beam.
Question 2.
What does a bending moment indicate?
Show hintHide hint
Consider the role of external forces on the beam's shape.
3Question 3.
What is shear force?
- Force acting perpendicular to the beam
- Internal force parallel to the beam
- Force that creates bending
Show hintHide hint
Think about cutting vs bending forces.
4Question 4.
True or False: Bending moments always increase as load increases.
- True
- False
Show hintHide hint
Consider the beam's support points.
Question 5.
A beam is subjected to a uniform load and a point load. Calculate the maximum bending moment and shear force at each section. Illustrate the shear and bending moment diagrams.
Show hintHide hint
Use areas to find corresponding moments in your diagrams.
Question 6.
For a cantilever beam with varying load distribution, derive expressions for shear and bending moments along its length.
Show hintHide hint
Break the problem into segments based on changes in load distribution.
