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.
