Abstract
The Knudsen forces (KF) were measured with a microcantilever in the capacitive mode. The deflection of the cantilever due to this force was calculated in the free-molecular regime, and the results agree with the observed effect. Presented measurements obey the semiempirical equation given by S(P) for the entire pressure range.
