The hanging mass is loaded at the free end of the cantilever beam and exerts the normal load required for wear testing on the test samples.
-

-
The relation between hanging mass and normal load can be calculated using moment about the pivot of the cantilever beam. The calculation has been done before and the relation is as follows:
-
"Normal load" = (22.0725 * "Hanging mass") - 12.37784676
-
Where normal load is in Newtons (N) and hanging mass is in kilograms (kg)
-
The relation and its computation table can be found in the "Lever calculations" excel file in the computer.

Ensure that the cable carrying the hanging mass is slotted into the groove at the free end of the cantilever beam before every tests. The cantilever beam will encounter violent vibrations if the cable is not in the groove, affecting test results.
