How to calculate PCD Hole Calculation IN Tamil
PCD Hole Calculation formula first method
X=COSƟ × PCD / 2
Y=SINƟ × PCD / 2
PCD 100MM . Equal space 5 no ((360/5=72))
1. X=SIN30 ×100/2 (X=0.866 ×50) X point =43.30MM
Y=COS30 ×100/2 (X=0.50 ×50) Y point =25.00MM
2.X=SIN30+72 ×100/2 (X=SIN102×100/2)X=-0.207 ×50 ((X Point =-10.40))
Y=COS102 ×100/2 (X=0.978 ×50) ((Y point =48.91MM))
3.X=SIN174 ×100/2 X point =-49.73MM
Y=COS174 ×100/2 Y point =5.23MM
4.X=SIN246 ×100/2 X point =-20.34MM
Y=COS246 ×100/2 Y point =-45.68MM
5.X=SIN318 ×100/2 X point =37.16MM
Y=COS318 ×100/2 Y point =-33.46MM
