b) 14
c) 21
d) 28

Answer 1

To prevent chocks from working free, at least 21 threads of manila line should be secured to the wheels.

Step-by-step explanation:

Chocks are devices used to prevent wheels from moving, especially in the context of vehicles or heavy machinery. To secure the chocks to the wheels, a manila line needs to be used. The question asks about how many threads of manila line are required to prevent the chocks from working free.

The correct answer is 21 threads or greater. This means that at least 21 threads of manila line should be used to secure the chocks to the wheels. Using fewer threads may result in the chocks becoming loose and not effectively preventing the wheels from moving.
