Why do they call the math thingy pie?
A pie chart is so called because it is circular - like a pie - and parts or proportions of the total are represented by wedge shapes - like slices of a pie.
What is a pie diagram?
A pie diagram or pie chart is an illustration to show how information breaks down into categories. There are examples in the related links. Basically each wedge in a circle is drawn in proportion to the amount of the whole it represents. For example if a pie chart was drawn for a collection of coins where half the coins were dimes and 1/4 of the coins were pennies and 1/4 of the coins were nickels, the pie would be cut in half and then one of the halves cut in half again. Each piece would represent one type of coin.
Is a wedge like an inclined plane?
Yes a wedge is an incline plane.
Is a doorstop a wedge?
yes, because a doorstop wedges the door. So it would be a wedge.
How do you calculate the mechanical advantage of a wedge?
It is the length of the sloped side of the wedge divided by its width.
