An inclined plane 13 ft long is used to slide a 260 lb box up to a loading platform 5 ft above ground level. A force of 160 lb is required. Find the efficiency of the inclined plane for this job. What force is required to overcome friction? What is the coefficient of friction between the plane and the box?
