Q3.) A front wheel drive industrial truck is used to move a solid 1500 kg cylinder with a diameter of 1 meter up the 30° incline. The coefficients of static and kinetic friction between the cylinder and both surfaces are 0.4 and 0.2, respectively. Determine the required tractive force between the truck's front tires and the horizontal surface necessary to begin moving the cylinder up the incline. Assume negligible friction between the rear wheels and the horizontal surface. Consider two possible ways the cylinder might move up the incline.
