What Is the Difference Between Static and Dynamic Loads?

31/3/2020, · ,Static Load, vs. Dynamic ,Load, The main difference between a ,static, and dynamic ,load, lies in the forces produced by the weight of an object. When ,static,, the ,load, remains constant and doesn't change over ,time,. With a dynamic ,load,, some outside factor causes the forces of the weight of the ,load, to change. Some of the factors that can affect a ,load, ...
