Question 13

One mooring line pulls a floating pontoon at an angle to a jetty. A force calculation record contains these three entries:

EntryForce recorded
1full mooring-line force
2component along the jetty
3component towards the jetty

All three entries are included when calculating the resultant force on the pontoon. Which change and reason corrects the record?

[1]
A

Delete the component along the jetty, because the other two entries together represent the full mooring-line force.

B

Reverse the full mooring-line force, because it must cancel the force represented by the two components.

C

Delete the full mooring-line force, because the two components together already have the same effect.

D

Delete both components, because each component separately has the same effect as the full mooring-line force.
