Algorhythmic is right. http://hyperphysics.phy-astr.gsu.edu/hb ... cline.html
Never argue with an idiot, they will drag you down to their level and then beat you with experience.
Before you criticize a man, walk a mile in his shoes. That way you'll be a mile away and he'll be shoeless.
You should only create problems, that only you know solutions to.

The San Diego regional put out a clarification on what they consider the correct definition for the IMA of a wedge. It is the January 3rd entry on this webpage: http://www.sandiegoso.org/divb2014/div_ ... imple.html

Re: Simple Machines B/Compound Machines C Question Marathon
Think about logically and in terms of the definition of IMA. Mechanical advantage will ALWAYS be your input distance divided by your output distance. In the case of an inclined plane, the slope length is considered the input because it is the actual distance that the load is being moved from point A to point B, though the inclined plane is actually different from the other simple machines as there is no specific distinction between output and input distances as effort is directly applied to the load. The wedge considers its overall length and not the slope length because the load is what is being split with the addiction of force. The output distance (the distance the load is split apart) is dependent on the overall length of the wedge because that is the distance put in, not the slope length.

What's the ideal mechanical advantage of a screw if it's radius is .5cm and the pitch is .03cm
