The length of a Slinky spring if stretched out strait, or flat, would be the circumference of one turn of the Slinky times the number of turns in the Slinky.
The circumference of a circle (shape of a slinky) is calculated as:
C = 2 x PI x R
Where: C is Circumference, R is the Radius, and PI = 3.1415...
The final equation would be as follows.
slinky_length = 2 x PI x R x
Each Slinky contains 67 feet of flat steel wire, and weighs approximately 1/2 pound.
About the same size as it is today but with a heavier gauge wire for the early ones. The woman that owned the patent died this year, 2009.
80 ft
Depends on how long the slinky is...
87 feet long
when stretched out, the worlds biggest slinky has been measured to be 40ft. and 2in.
a slinky a slinky fun for everyone a slinky a slinky
I think that the Slinky original is the best. It's bigger than the Slinky Jr. and will most likely go faster! BTW, I LOVE Slinky! Chow, ;)
They vary in length, but are usually about 87 feet long at maximum.
A slinky is stretched across a classroom to 9 meters. A compression travels along the slinky at a velocity of 2 m s . How long does it take to travel the entire 9m length of the classroom?
Slinky coils
The most common materials used for making a Slinky are metal and plastic. However, there are many materials that can be used as long as they get cut into that spiral shape.
depends on the slinky
To fix and stretched out slinky you should put the slinky in hot (not boiling water) for two min, and then take it out and place something heavy on the slinky.
a slinky is necessary because to have fun
