The gear-pulling assembly shown consists of a crosshead CF, two grip arms ABC and FGH, two links BD and EG, and a threaded center rod JK. Knowing that the center rod JK must exert a 4800-N force on the vertical shaft KL in order to start the removal of the gear, determine all forces acting on grip arm ABC. Assume that the rounded ends of the crosshead are smooth and exert horizontal forces only on the grip arms.
