- Tensile Strength of Plant Fibers- Core Practical
- Variables
- Independent
- Tensile strength of different plant fibers
- Dependent
- Mass plant can hold before it breaks
- Control
- Amount weight goes up by
- So results are accurate and comparable
- length of fibers
- So results are comparable
- Mass added to the same part of plant
- Different areas of fiber could have weakness
- Temperature
- Can affect strength of fiber
- Moisture in air
- Less moisture more brittle fiber becomes
- Amount weight goes up by
- Independent
- Equiptment
- Plant fibers
- Forceps
- Bucket
- Ruler
- Clamp stand
- Sissors
- Vernier calliper
- Method
- 1. Extract the plant fiber using forceps or by placing submerged in water then peeling them
- 2. Cut the fibers to the same length
- 3. Attach fibers to clamp stands
- 4. Add mass to the plant fiber until it breaks and record the mass it breaks at
- 5. Repeat the results
