2.7. Examples

Try these first

1. 1.

   Define a concentrated load.

   Hint

   Think about how forces affect beams.

2. 2.

   What is a statically determinate beam?

   Hint

   Recall how many supports it has.

3. 3.

   What is a concentrated load?

   • A load distributed over a length
   • A load applied at a single point
   • A load changing with time

   Hint

   Think about the application of force on a beam.

4. 4.

   Statically indeterminate beams can be solved solely with equilibrium equations.

   • True
   • False

   Hint

   Think about how many supports there are.

5. 5.

   A cantilever beam of length 8 m is subjected to a point load of 1000 N at the free end. Calculate the reactions at the fixed support.

   Hint

   Remember to express reactions and moments, considering the beam's support constraints.

6. 6.

   Analyze a continuous beam with two spans of 5 m each, uniformly loaded with 2 kN/m. Determine the internal forces at mid-spans.

   Hint

   Breaking the spans into segments can simplify calculations.
