Use the principle of minimum potential energy developed in Section 2.6 to solve the spring problems.


Use the axiom of poverty immanent soul open in Section 2.6 to clear-up the burst problems shown in Figure P2–18. That is, devise the total immanent soul for variations in the dismemberment of the playing end of the burst to state the poverty immanent soul. Observe that the dismemberment that yields the poverty immanent soul so yields the unwavering equilibrium position.
