This is for determining the shear strength of both remoulded and undistrubed soils. It consists of a torque head adjustable in height to enable the vane to be lowered into the specimen. Rotation of the vane is by mean of a hand wheel which operates a worm gear arrangement turning the upper end of a calibreted torsion spring. Two rates of rotation are incorporated. The vane shaft is attached through the hollow upper shaft to a reset table pointer, Which indicates the angle of torque on dial graduated is degree. The dial reading multiplied by spring factor gives the troque. A container is also supplied. Complete with a set of springs,one each of approx. 2 kg. cm., 4kg.cm., 6 kg cm and 8 kg.cm.
