<< >>
Usage conditions apply
The rotation of a shaft representing results calculated by the differential analyzer were transmitted to a tracer that drew the results on an output table. This is the carriage for the tracer point, with tracer point. It is a large open arrangement of steel shafts, with one shaft is perpendicular to a double set.
Parts of the Bush differential analyzer surviving at the Smithsonian have museum numbers MA.314824 and 1983.3002.01 through 1983.3002.89.
