Either describe, sketch, or take a picture of a real system whose motion can be described by a single coordinate. At least one of the components must have mass, and at least one must have stiffness. For each of the components, indicate if it has mass, stiffness, and/or damping. Also explain if this is a rotational or translational system and why. The system you pick must be something you encounter in everyday life and may not be a system that has been discussed in class.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
