✦ Synopsis

A direct method is presented for measuring the shear modulus of gels. The method is based on torsional oscillations of a gel sample. Only small distortions are introduced, ensuring linearity of response. The forces involved do not have to be measured directly; they are inferred from the oscillation period and the geometry of the system. This method is simple, quick and economical.
