A hydraulic-lift truck carries a shipping container on the inclined loading ramp in a warehouse (Figure P4.5). The 12-kN and 2-kN forces act on a rear tire as shown in the directions perpendicular and parallel to the ramp. (a) Express the resultant of those two forces as a vector using the unit vectors i and j. (b) Determine the magnitude of the resultant and its angle relative to the incline.
