wondering if there is a formula i can use to calc bend curve of a mast i have.
flex distribution bottom 63.4% / top 76.8% for a 400mm mast.
tia.
Try this:
Constant Curve
Any mast with a base - tip percent of mid-point difference in the 10% - 14% range is considered to be a 'constant curve' mast. The 'classic' definition of a constant curve mast is a mast having a 76% tip defelection percentage and a 64% base deflection percentage. These masts are often labeled as 12% constant curve masts.
Flex Top
Any mast with a base - tip percent of mid-point difference in the 18% - 22% range is considered to be a 'flex top' mast. The 'classic' definition of a flex top mast is a mast having a 82% tip defelection percentage and a 62% base deflection percentage. These masts are often labeled as 20% flex top masts.
Combi Curve
Any mast with a base - tip percent of mid-point difference in the 14% - 18% range is considered to be a 'combi curve' mast. The 'classic' definition of a combi curve mast is a mast having a 79% tip defelection percentage and a 63% base deflection percentage. These masts are often labeled as 16% combi curve
masts.
What you have there pretty well a classic 'Constant Curve' mast @13.4% difference.
