Repeated bending causes tiny cracks to form in the nail, weakening its structure. Over time, these cracks can accumulate and propagate, eventually leading to a complete fracture of the nail when subjected to sufficient force.

what kind of energy does a bent ruler have
A bent ruler has potential energy stored in its elastic deformation. When the ruler is bent, energy is stored in the form of mechanical potential energy, which is released when the ruler returns to its original shape.
When white light passes through a prism, blue light is bent the most followed by violet, while red light is bent the least. This separation of colors is known as dispersion.
When light rays are bent and brought together, they are converged at a single point, forming an image. This convergence point is known as the focal point.
Red light is bent the least by a prism because it has the longest wavelength among the visible light spectrum, causing it to experience the least amount of deviation when passing through a prism.
