Sail Force Formula:
Enter the values of lift force L(Newton) , drag force D(Newton) & wind angle a(degree) to determine the value of sail force F(Newton) .
Sail Force Calculator:
The sail force F(Newton) in Newton is equal to the lift force L(Newton) in Newton into multiply the wind angle sin a(degree) in degree and subtracted to the drag force D(Newton) in Newton into multiply by the angle cos a(degree) and addition of the lift force L(Newton) in Newton into multiply the wind angle cos a(degree) in degree and addition fo the drag force D(Newton) in Newton into multiply by the angle sin a(degree).
The formula of the sail force can be writtern as,
F(Newton) = [ L(Newton) * sin a(degree) – D(Newton) * cos a(degree) ] + [ L(Newton) * cos a(degree) + D(Newton) * sin a(degree) ]
Here,
F(Newton) = sail force in Newton
L(Newton) = lift force in Newton
D(Newton) = drag force in Newton
a(degree) = wind angle in degree
Sail Force Calculation:
1)To find the sail force and lift force 50N and drag force 20N and wind angle 45degree
Answer
SF = [ L* sin(a) – D * cos(a) ] + [ L* cos(a) + D * sin(a) ]
SF = [ 50 * sin(45) – 20 * cos (45) ] + [ 50 * cos(45) + 20 * sin (45) ]
SF = 75.32N.
