Challenge Problems
Push your limits with challenges.
Question 1
A vertical point load is applied to an elastic soil medium at coordinates (0,0) with magnitude P. Explain the mathematical steps to compute the stress at a point an arbitrary distance away, (x,y).
💡 Hint: Think about how stresses transition in the medium from the point load.
Question 2
Critique the use of the Dirac delta in practical engineering scenarios. What alternatives might be necessary for modeling finite duration loads?
💡 Hint: Consider the implications of applying instantaneous vs. continuous loads.
