The purpose of this project was to test if the line would break at the manufactured specified rating and to measure and plot the stress vs. strain curve for the fishing line. The type of fishing line that we used was nylon.Fishing Line Brands:Du Pont: Stren Sport Fisher: Eagle ClawZebco: Omniflex Trilene: XL Super StrongTrilene: XT Extra Tough

12 Lb Test Fishing Line

Du Pont: StrenMade in U.S.A.

The break point of the 12 lb test was at 13.3 lbs.Line diameter: 0.0125 inModulus of Elasticity (E) : 561709

14 Lb Test Fishing Line

Sport Fisher: Eagle ClawMade in Brazil

The break point of the 14 lb test was at 12.13 lbs.Line diameter: 0.0135 in.Modulus of Elasticity (E): 451959

15 Lb Test Fishing Line

Zebco: OmniflexMade in China

The break point of the 15 lb test was at 14.33 lbs.Line Diameter: 0.015 inModulus of Elasticity (E): 429428

25 Lb Test Fishing Line

Trilene: XL Super StrongMade in U.S.A.

The break point of the 25 lb test was at 24.26 lbs.Line Diameter: 0.018 inModulus of Elasticity (E): 285522

30 Lb Test Fishing Line

Trilene: XT Extra ToughMade in U.S.A.

The break point of the 30 lb test was at 33.08 lbs.Line Diameter: 0.021 inModulus of Elasticity (E) : 231930

Stress vs. Strain for all Tests

Breaking Points of the fishing lines

Tested strength as a percent of rated strength

Are test showed that only the 30lb Trilene and 12lb Stren had a greater tested strength then they were rated for.

The 14lb Eagle Claw broke almost 14% its rated strength.

The other two, the Zebco Omniflex 15lb, and the Trilene Super Strong 25lb, both broke relatively close to their rated strengths, within 5%.
