Which equation can you use to calculate the mechanical advantage of a simple machine?
Supreeta N.
Mechanical advantage is the ratio of the force required without the use of a simple machine to that needed when using the simple machine. Compare the force to lift an object with that needed to slide the same object up a frictionless incline and show that the mechanical advantage of the inclined plane is the length of the incline divided by the height of the incline $(d / h$ in Fig. $4.25).$
