Challenge Problems

Push your limits with challenges.

Question 1

A beam carries a concentrated point load represented by a Dirac delta function at a location 'a'. How would this load change if it were applied over a 0.1m length instead?

💡 Hint: Consider how changing from delta function to a rectangular could affect your integrals.

Question 2

In an engineering problem, explain the implications of assuming a Dirac delta function when analyzing a force that actually spreads over a small area.

💡 Hint: Think of how forces act over time and physical space in real conditions.
