This research work deals with the development of the shearbox
apparatus by introducing a micro-computer to automatically collect
all the results, and to apply normal and shear stresses. A continuous
statement of time, channel number, and transducer input and
output is produced for each test, the sequences of applied rates of
displacement and normal stresses for which were programmed. [Continues.]
