Figure 23.7 shows two cantilevers, the end of one being vertically above the other, and is connected to it by a spring AB. Fig. 23.7 Initially, the system is unstrained. A weight W placed at A causes a vertical deflection at A of δ1 and a vertical deflection at B of δ2. When the spring is removed, the weight W at A causes a deflection at A of δ3. Find the extension in the spring, when it is replaced and the weight W is transferred to B. SOLUTION. Given: Weight at A = W ; Deflection of A (with sprin
