1.8 Determination of equivalent moment of restriction forces
during one cycle of mechanism’s steady motion

Magnitude of equivalent moment of restriction forces is

Useful effort F 0  1150 N acts during working motion of the
mechanism, i.e. at motion of the slider to up. If the slider moves
down – F 0  0.
