Could someone explain dynamic and static load?

In non technical terms please

 

Static loads are loads that exert a constant amount of force, while dynamic loads exert varying amounts of force upon the structure that is upholding them. A simple example of a static load is the weight of a bridge span upon the bridge pilings holding it aloft. A truck moving across that same bridge span would be exerting a dynamic load on the pilings.

Standing stationary in one place on the floor would be a static load, jumping up and down would create a dynamic load.

 

So the Weight load on a Cap on a Taco would Static, Correct. And the load the manufacture place on Caps would be ?

 

Yes, because it doesn't change... Just adds weight to the total static weight.

 

The variations of dynamic loads can be due to changes in mass, direction of movement, pressure or speed of movement. Like something in the bed of your truck not secured - as it shifts around when you brake, turn or accelerate, the dynamic load on your suspension and tires would vary depending on those types of variables...

 

Simply put, a 100 lb RTT on your parked bed rack would be 100 lbs STATIC. That same RTT will impart more DYNAMIC load when you drive off a tall curb. Same as if someone tossed you that same RTT from the 2nd story window...it will weigh more, or put more load on what it's sitting on.
