Challenge Problems
Push your limits with advanced challenges
Given a truck with a total weight of 40 kN distributed on 4 wheels, calculate the contact pressure if the contact area per wheel is circular with a diameter of 0.6 m.
💡 Hint: Remember the contact pressure formula and how to calculate the area of a circle.
Analyze a scenario where a pavement experiences 10,000 load applications of 80 kN each. Discuss how this may affect the pavement’s longevity, considering the cumulative effect.
💡 Hint: Look into how repeated stresses contribute to material fatigue.
