Influence of container shape, partitions, frequency, distance, and height level on the maximum acceptable amount of liquid carried by males

The problems associated with liquid carriage (moving e.g., sloshing, and force unbalance) were investigated experimentally and the effect of several task variables on the maximum acceptable amount of liquid carried by males was determined. Five different task variables were studied: shape of non-collapsible containers (rectangular, cylindrical, barrel), height of carry (knuckle height, elbow height), frequency of carry (once/minute, once/4 minutes), distance of carry (3.05 m, 9.14 m), and presence and absence of partitions in a container. Thirteen male college students voluntarily participated in the experiment. The psychophysical methodology was employed and ‘the maximum acceptable amount of liquid carried’ was determined. Each subject performed 48 treatment combinations. Statistical analysis showed that the liquid carrying capacity of males is not influenced by the shape of the non-collapsible, as opposed to collapsible type, containers. The maximum acceptable amount of liquid carried, however, is incre...
