6.0 t
6,0 t
b
5.0 t
5,0 t
c
7.0 t
7,0 t
Correct answer
d
3.5 t
3,5 t
Why?
The leg angles of the wire rope sling (zawiesie linowe) are measured from vertical: a larger angle increases leg tension and reduces the permissible load. Changing from 45° to 60° gives approximately 70% of the previous capacity, so 10 000 kg becomes approximately 7000 kg, or 7.0 t. Do not divide the capacity by two, because 10 000 kg already applies to the whole sling.
