The stationary excavator is vertically lifting the load at A with acceleration ao = 2.5 m/s².lf l = 4 m, w= 3.65 m, d = 0.82 m, the mass of

the load at A is mA = 8300 kg, and the total mass of the excavator is mG = 20,000 kg, determine the equivalent normal force acting on each of the two tracks and its location relative to the rear of the track 8. The center of mass of the excavator is at G.
