Figure P.15.24 shows two cantilevers, the end of one being vertically above the end of the other and connected to it by a spring AB. Initially the system is unstrained. A weight, W, placed at A causes a vertical deflection at A of dj and a vertical deflection at B of 82. When the spring is removed the weight Wat A causes a deflection at A of 83. Find the extension of the spring when it is replaced and the weight, W, is transferred to B. Ans. 82(81–8,)/(8, 8,)

Figure P.15.24 shows two cantilevers, the end of one being vertically above the end of the other
and connected to it by a spring AB. Initially the system is unstrained. A weight, W, placed at
A causes a vertical deflection at A of ô1 and a vertical deflection at B of ô2. When the spring is
removed the weight Wat A causes a deflection at A of ô3. Find the extension of the spring when it is
replaced and the weight, W, is transferred to B.
Ans. 82(8,-8,)/(8, 8,)
