Stützlast

The German word "Stützlast" is a noun composed of two parts:

• Stütz: Derived from "stützen," meaning "to support" or "to prop."
• Last: Means "load" or "weight."

Meaning:
"Stützlast" refers to the supporting load or axle weight — specifically, the force or pressure exerted on a support point, such as the hitch load of a trailer on a car’s tow bar.

Similar words:

• Belastung – load or stress (more general)
• Last – load or burden
• Druck – pressure (often more about force per area)

Difference:
While Belastung and Last refer broadly to any load or stress, Stützlast specifically denotes a supporting or bearing load typically related to structural or mechanical support points. It is more precise in contexts like vehicle towing or construction.
