Abstract

We discuss the possible effects of gravitational-wave stochastic background on the performance of a pendulum device such those used in precise measurements of the gravitational constant G. The variation DeltaQ of the quality factor Q of the pendulum induced by the stochastic background is evaluated, by using as numerical input the results obtained in gravitational antennas experiments. It is found \DeltaQ\ similar to 10(-10), completely negligible with respect to a typical value Q similar to 10(5).
