The 3000 kg front wheel drive SUV shown in the figure is attempting to tow the log along level ground. The coefficient of static friction between the log and the ground is u = 0.8, and the coefficient of static friction between the front wheels and the ground is u= 0.4. 0.5 m 1.6 m 1.2 m The rear wheels of the SUV are free to roll (no friction), and you can assume that the engine can develop enough torque to cause the front wheels to slip. You can assume that the log cannot tip. Determine the maximum weight of the log that the SUV can tow. Draw all necessary FBD's and put units on your answers.
