Question:

A simple lumped-parameter model of a building, shown as the inverted link in Figure 6.68, can be used for preliminary study of earthquake dynamics. Derive the equations of motion for this two degreeof-freedom system using

(a) Newton's second law, and

(b) Lagrange's equation. Let \(y(t)\) be the prescribed ground motion, and \(x(t)\) be the absolute position of the mass \(m\).
