In designing the toggle press shown, n turns of the worm shaft A would be required to produce one turn of the worm wheels B which operate the cranks BD. The movable ram has a mass m. Neglect any friction and determine the torque M on the worm shaft required to generate a compressive force C in the press for the position () = 90°. (Note that the virtual displacements of the ram and point D are equal for the () = 90° position.)
