6-63 The wrecker truck of Fig. P6-63 has a weight of 15,000 lb and a center of gravity at G. The force exerted on the rear (drive) wheels by the ground consists of both a normal component By and a tangential component B, while the force exerted on the front wheel consists of a normal force Ay only. Determine the maximum pull P the wrecker can exert when e- 30° if B, cannot exceed 0.8B, (because of friction considerations) and the wrecker does not tip over backward (the front wheels remain in contact with the ground). 9. 10 ft 4 ft 6.5 ft - 8 ft+5 ft
