4.5 Mast tie forces
The mast tie forces can be found in the following tables, depending on the assembly height
and assembly situation. The peak forces occurring for the represented assembly geometry
are given;
they do not yet include any safety factors
.
4.5.1 Mast tie forces for a car
The assembly geometry shown in
Fig. 4 shows the corresponding
mast tie forces Ax, Ay and By from
wind forces.
Distances according to Fig. 3.
Mast tie distance = 30 ft (9 m)
