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