Question:

The spring constant for a helical coil spring, k

,

theoretically follows the form shown where d

(

lower case

)

is the wire diameter, D

(

UPPER CASE

)

is the mean diameter of the coil, na is the number of active coils and G is a material property called the shear modulus.

Out side diameter OD

= 13

Wire diameter d

= 1600

microns

Active coils na

= 63

modulus G

= 66

/

.

.

Also assume that all the measurements have an uncertainty of

2.7 %

of the average. Use the High

-

Low method to determine

(

)

k and

(
