The truck has M and a center of mass at G. The truck is traveling up an incline of angle θ. Determine the greatest load it can pull if (a) The truck has rear-wheel drive while the front wheels are free to roll, and (b) The truck has four-wheel drive. The coefficient of static friction between the wheels and the ground is μst and between the crate and the ground, it is μsc. Units Used: kN = 103 N

Mg = 1000 kg

Given:

θ = 10 deg

M = 1.25 Mg a = 600 mm

μst = 0.5 b = 1.5 m

μsc = 0.4 c = 1 m

g = 9.81m/s2d = 800 mm
