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 ΔQ 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 |ΔQj ~ 10-10, completely negligible with respect to a typical value Q ~ 105 .
