6-63 The wrecker truck of Fig. P6-63 has a weight of15,000 lb and a center of gravity at G. The force exerted onthe rear (drive) wheels by the ground consists of both anormal component By and a tangential component B, whilethe force exerted on the front wheel consists of a normalforce Ay only. Determine the maximum pull P the wreckercan exert when e- 30° if B, cannot exceed 0.8B, (becauseof friction considerations) and the wrecker does not tip overbackward (the front wheels remain in contact with theground).9.10 ft4 ft6.5 ft -8 ft+5 ft

Given : Weight of the truck W = 15000lb Bx(max) =0.8By θ = 30°

1. For this series of 4 questions, a rider rides in a car that is connected to a 4-m rod, and rotates about the z axis. The rod of negligible mass is subjected to a constant couple moment of M, and the engine of the car supplies a traction force of F. Neglect the size of the car. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 3) If the rod is subjected to a constant couple moment of M = 800 N•m, and the engine of the car supplies a traction force of F=11•t N to the wheels, where tis in seconds, what is the magnitude of the angular impulse from the moment and the force to the car-rider system in kg•m²/s from t = 0 to t = 5.7 s? Your answer must include 1 place after the decimal point. Your Answer: Answer M 4 m F
