Conservation of energy is a fundamental principle in physics that states that the total energy of an isolated system remains constant over time. In other words, energy cannot be created or destroyed, only transformed from one form to another. However, the conservation of energy is not only applicable under specific circumstances.

a) Static load is applied:
When a static load is applied, it means that the load is not moving or changing over time. In this case, the conservation of energy is applicable because the energy of the system remains constant. The potential energy stored in the load and the surrounding objects is balanced by the external force applied, such as gravity or compression forces.

b) Dynamic load is applied:
When a dynamic load is applied, it means that the load is in motion or changing over time. In this case, the conservation of energy is still applicable. The kinetic energy of the load is balanced by the work done by external forces, such as friction or air resistance. The total energy of the system, including potential and kinetic energy, remains constant as long as no external energy is added or lost.

c) Can be anything:
The conservation of energy is a fundamental principle that applies to all physical systems, regardless of the nature of the load or the type of energy involved. Whether it is a static load, dynamic load, or any other type of load, the principle of conservation of energy still holds true. Energy may be transferred or transformed from one form to another, but the total energy of the system remains constant.

d) Large load is applied:
The size or magnitude of the load does not affect the applicability of the conservation of energy principle. Whether the load is small or large, the conservation of energy still applies. The total energy of the system is conserved, regardless of the magnitude of the load or the forces involved.

In conclusion, the conservation of energy principle is applicable in all situations, including when a static load is applied. This principle holds true for static and dynamic loads, as well as for loads of any size or magnitude. The conservation of energy is a fundamental law of nature that governs the behavior of physical systems.
