🔍 Key Concepts

• How mooring tension gauges work to measure the pull in a line • Common types of load cells used in marine winches and mooring systems • Difference between hydraulic systems and purely mechanical devices

💭 Think About

• Which option lists two categories you would realistically find on physical mooring tension indicators aboard ships? • Do any of the options use terms that sound more like general physics words rather than standard load-cell types? • Think about what type of system can translate line tension into a readable dial or display without relying on electrical sensors.

✅ Before You Answer

• Eliminate any pair that does not sound like established load-cell technologies used in industry. • Ask: can this type of cell practically be built into a mooring winch or fairlead and survive the marine environment? • Check that both items in the chosen option are commonly paired together when talking about mooring tension gauges, not just random technical-sounding words.
