Challenge Problems
Push your limits with advanced challenges
A structure experiences a ground motion of 0.5 m upward during an earthquake, and a mass within the structure moves 0.6 m upward. Calculate the absolute displacement of the mass.
💡 Hint: Always remember to add the movements to find the absolute displacement.
If a mass experiences a relative acceleration of 4 m/s² while the ground has an acceleration of 2 m/s², what is the absolute acceleration of the mass?
💡 Hint: Combine the effects of both the mass and ground acceleration for total understanding.
