CALCULATION OF THE FORCE NECESSARY
The calculation is made without considering the loads due to atmospheric agents.
Key to symbols
F = Force required to open in N (Newton)
P = Weight of the window (only moveable part) in kg (kilogrammes)
C = Opening travel of actuator in cm. (Centimetres)
H = Height of the openable part of the window in cm. (centimetres)
