    Impact
In summary, the difference between impact and sudden loading is that impact loading involves a collision process where loads are dropped from a height, resulting in increased initial stresses and deflections. On the other hand, sudden loading refers to loads that are applied quickly rather than gradually or slowly, with an example being placing an object close to a beam and then dropping it, causing initial stresses and deflections to be higher before dampening restores the beam to a static condition. There may not be a formal definition for these terms, but this is how they are interpreted.

I don't know if there is a formal definition, but I interpret sudden loads as loads that are applied quickly rather than gradually or slowly, for example, if you slowly apply an object
to the end of a cantilever beam, its stresses and deflections will be in accord with the laws for equilibrium , whereas if the object was placed very close to the beam and them dropped, stresses and deflections would initially be about twice as much until dampening restored the beam to the static condition. Impact loads, however , might be dropped from a height in a collision process, thereby greatly increasing initial stresses and deflections.
 

1. What is the difference between impact and sudden loading?

Impact loading is a type of loading where a force is applied gradually over a period of time, while sudden loading is a type of loading where a force is applied suddenly and without warning.

2. Which type of loading is more damaging to structures?

In most cases, sudden loading is more damaging to structures as it causes a higher stress concentration in a shorter amount of time, resulting in a higher chance of failure.

3. Can impact loading be controlled or prevented?

Yes, impact loading can be controlled or prevented through various methods such as using shock-absorbing materials or implementing design changes to distribute the force over a larger area.

4. What are some examples of impact loading?

Examples of impact loading include collisions between objects, dropping heavy objects, and sudden changes in wind or water pressure on structures.

5. How is the effect of sudden loading measured?

The effect of sudden loading is measured using various parameters such as stress, strain, and deformation. These measurements can help determine the extent of damage caused by the sudden loading event.
