The truck has a masS oad it can pull if: a) the truck has rear-wheel drive while the front wheels are free to roll. (b) the truck has four-wheel drive. The coefficient of static friction between the wheels and the ground is µs=0.5, and between the crate and the ground, it is µs=0.4. Note: Rear-wheel drive means the rear wheels must slip and four-wheel drive all four wheels must slip. So in this problem, the wheels must be on the verge of slipping, max. friction force.

Question
The truck has a mass of 1.25 Mg and a center of mass at G. Determine the greatest load it can pull if: (a) the truck has rear-wheel drive while the front wheels are free to roll. (b) the truck has four-wheel drive. The coefficient of static friction between the wheels and the ground is µs=0.5, and between the crate and the ground, it is us=0.4. Note: Rear-wheel drive means the rear wheels must slip and four-wheel drive all four wheels must slip. So in this problem, the wheels must be on the verge of slipping, max. friction force. 800 mm 600 mm F1.5 m--–1 m 10°
