Which material is commonly used in flexible measuring tapes for its light weight and non-conductive properties?

• A. Wood
• B. Metal
• C. Fiberglass
• D. Cloth

Answer: (C)

Flexible measuring tapes need a material that is light, durable, and an electrical insulator. Fiberglass fits these needs well: it’s lightweight, flexible enough to wrap around objects, and a strong insulator, so it won’t conduct electricity. It also resists corrosion and maintains accurate measurements because it has low stretch and good dimensional stability. In comparison, wood is heavier and less flexible for a tape, metal conducts electricity and is heavier, and cloth can stretch and wear over time, reducing accuracy. So fiberglass is the best choice for its combination of light weight and non-conductivity.
