摘要：

We describe an easy to assemble torsional pendulum which can be put together for about $5 from parts available at any hardware store. The accuracy obtained in the measurement of the modulus of rigidity, G, is comparable the accuaracy obtained with the more expensive commercially available student models. © 1979 American Association of Physics Teachers
