ABSTRACT
Examples of intermittent laws of motion, both of the alternating type and progressive type, are reported in Figure 7.1.
According to Figure 7.1, the main quantities bound to the de—nition of intermittent motions are
• the period T; • the ratio υ between the advancement time ta and the period T, de—ned as ta /T; • the angular lift Ψ, that is, the angle of rotation implemented at each
advancement; • the number of stations or number of stopping positions n, de—ned as 2π/Ψ.
