7. Theory of Structures

Try these first

1. 1.

   What is a bending moment?

   Hint

   Consider the effect of forces on beams.

2. 2.

   Define equilibrium in the context of structures.

   Hint

   Think about forces balancing out.

3. 3.

   What is a bending moment?

   • A force acting on a beam
   • An internal moment that causes a beam to bend
   • A type of loading

   Hint

   Think about what happens to a beam when it is loaded.

4. 4.

   Equilibrium condition in structures ensures that:

   • True
   • False

   Hint

   Consider how forces interact in a stable system.

5. 5.

   A cantilever beam with a length of 4 meters is subject to a uniform distributed load of 200 N/m. Determine the maximum bending moment at the fixed support.

   Hint

   Understand the effect of uniform loading on moment calculations.

6. 6.

   Calculate the bending moment at a point 1 meter from the left support on a simply supported beam of 6 meters with a central load of 600 N.

   Hint

   Break down the problem using equilibrium and diagram techniques.
