Consider a system where a mass is subjected to ground motion. Analyze how modifying the stiffness of the system changes its response to seismic loads.
💡 Hint: Think about the relationship between stiffness and response frequency.
Sketch a free body diagram for a mass experiencing both gravitational and inertial forces during ground motion. Indicate all forces acting on the mass.
💡 Hint: Remember to draw arrows to signify the direction and magnitude of each force.
