You’re using a system of multiple simple machines to move a 1500 N load up a height of 2 meters. You have a wheel barrow which is a combination of a lever and a wheel/axle, and you’ll be using a ramp (inclined plane). What length ramp do you need to achieve the actual mechanical advantage from using the wheel-barrow? The height is set at 2 meters. Assume the efficiency of the inclined plane (ramp) is 100% (so your ideal, or design, mechanical advantage is your actual mechanical advantage).
