What reading level is Physics book?
To quickly assess the difficulty of the text, read a short excerpt:
For this particular plane, then. Resistance = Effort X 4; or the greatest resis- tance that can be overcome with this plane is equal to 4 times the effort applied. If then we wish to know the re- sistance that may be overcome with this plane when an effort of 100 pounds is applied, we have only to make the mental calculation, Resistance = 100 X 4 = 400 pounds.
Conversely if we are to raise a weight of 600 pounds with this plane, the effort =» H^ = 150 pounds.
This number, which tells relatively... how great a resistance can be overcome with a machine when a given effort is applied to it, is called the mechanical advantage of the machine.
The mechanical advantage of a machine is the number by which the effort must be multiplied to get the resistance.
From this definition it follows that Effort X Mechanical Advantage = Resistance.
