Question #604
In the image below, the symbol α denotes:
Na zdjęciu poniżej symbol α oznacza:
Open full-size illustrationa
the included angle between the sling legs
kąt rozwarcia cięgien zawiesia
Correct answer
b
the maximum apex angle
maksymalny kąt wierzchołkowy
c
a value determining the sling's lifting capacity
wartość określającą udźwig zawiesia
d
the sling's working load limit (DOR)
DOR zawiesia
Why?
The arc marked α runs between the two legs and shows the included angle between the sling legs (kąt rozwarcia cięgien zawiesia). It is the angle of the arrangement shown, rather than a designation of the maximum permitted angle. For the symmetrical arrangement in the drawing, α = 2β.
