1.1. Introduction

Try these first

1. 1.

   Define non-uniform bending.

   Hint

   Think about how moments vary along a beam.

2. 2.

   What does a distributed load affect in beam analysis?

   Hint

   Consider how loads influence internal forces.

3. 3.

   What defines non-uniform bending in a beam?

   • Constant moment
   • Variable moment
   • No moment

   Hint

   Think about the condition of the bending moment.

4. 4.

   True or False: A distributed load affects only the bending moment.

   • True
   • False

   Hint

   Consider what happens to forces in a beam.

5. 5.

   A 5m cantilever beam has a triangular distributed load that varies from 0kN at the wall to 10kN at the free end. Calculate the shear force and bending moment at 2m from the wall.

   Hint

   Break down the load into sections; think about the moments created.

6. 6.

   A simply supported beam with varying distributed loads is subjected to calculate the point of maximum bending. Describe your method.

   Hint

   Start with the boundary conditions and work towards finding internal forces.
