Determine the percentage of the population that would be accommodated on each measure by a
public bench that was 22 inches deep and 19 inches off che ground.

we have to estimate percentage of
of the population who can reach the
material on a storage shelf of hight
of 2060 mm by defining the user population
As we see here from the table given
that we could design for the average user

5. Ar the Acme Flashlight and Lantern plant, an expensive machine was designed and custom built
to automate the label-riveting operation on flashlight rubes. The worker’s task involved the placing
of oval shaped plastic labels (1 in major axis length, yn in minor access length) on a rotating table
(1 ft diameter) with very close fit requirements. Labels were picked up from the cable by suction and
positioned on a tube delivered to the riveting station by a conveyer mechanism. Instantaneously,
the label was riveted to the tube at both ends. The plant was experiencing many rejects on this
operation, the majority of rejects having the label missing.
Give a brief description of the Fundamental Ergonomic
Model and briefly explain how it might be
applied to determining the cause of the rejects at Acme Flashlight and Lantern
