How do I get the included angle of the measurement I took, and then find the arc length i.e. the deflection at the sample?
I need to solve for n and then find the L for the smaller radius at each testing position. |
*The circumference is pi X diameter and represents 360-degrees.
*L/C would be the percentage of 360-degrees and spit n out.
* The 'new' circumference at the different station would be pi X D,which would constitute 360-degrees.
*If you measure n there,then L= [[ n/360 X[ ( 2 X radius) X pi]]
