Inclined Plane (Ramp)
A tilted flat surface that lets you raise a load over a longer horizontal distance instead of straight up.
MA = length of slope / vertical height
A ramp 5 m long and 1 m high: MA = 5. Push with 1/5 the weight — but over 5× the distance.
More gradual ramp = greater MA. Steeper ramp = less MA.
