m=65
(AMA / IMA)100 Where AMA represents the actual mechanical advantage and IMA represents the Ideal Mechanical advantage. AMA = Fr/Fe where Fr equals the force of the resistance from the fulcrum, and Fe equals the force of the effort. IMA = De/Dr where De equals the Distance of the effort from the fulcrum and Dr equals the distance of the resistance from the fulcrum
A whistle or some other mechanical means (horn) to make a sound AND a bell
The 'ideal' mechanical advantage is length of the effort arm/length of the load arm .
it equals LxL+WxW
A = bh (multiply length x width).
Ideal Mechanical Advantage
Length/ Hieght
Length times width equals area
The length of the hypotenuse of a right triangle if AC equals 6 and AD equals 5 is: 7.81
Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
The ideal mechanical advantage of an inclined plane is a ratio describing the length one has to travel to raise a load by a desired height. To obtain this ratio, divide the length of the plane's sloped face by the height of the inclined plane. IMA = Slope length / height
In order to find length BC the length of AC or length of the hypotenuse must be given
