A ball is attached by two springs as shown in the left figure( |wwOww| ).If the mass is displaced a distance ⊿x below the equilibrium position h. Determine whether vertical SHM is possible for the system shown. If so, find the natural frequency. [assume that the vertical extension ⊿x is corrspond with the extended length d' of the spring and (1 + a)to the power of -b is close to 1-ab if a is small.]

What does the symbol ⊿ supposed to represent?

Are the springs arranged horizontally?

Sorry about that....⊿x means a small distance x, i can't find a perfect triangle.

Since the mass have weight, the springs is not arranged horizontally in equilibrium position.

It can be explained more clearly if i can send you a diagram.
