Review of system of angular do flip embryos around the fulcrum, when Fulcrum had the baby (pegs), K6 = 1, when Fulcrum present large exposure, K6 = 1.2
Review preparations torque coefficient flip around the fulcrum, the fulcrum has little contact surface (bottom), K6 = 1, when the fulcrum has a large contact surface, K6 = 1.2
