Simple Machines

There are six simple machines. The screw, wedge, inclined plane,pulley, and lever. These simple machines all have different mechanical advantagess. The formula for the lever IMA=Din/Dout which is Ideal Mechanical Advantages  = distance from input force to fulcrum/ distance from output force to fulcrum. The formula for just regular mechanical advantage is Mechanic advantage = Output force/Input force.
The formula for inclined plane is Ideal Mechanic advantage = length of inline / height of incline. Te formula for wheel and axle is Ideal Mechanic advantage = Radius of Input / Radius of Output
