Tensile Testing Constraint

Our purpuse was to test how much for this tensile could hold. From this we will learn that before using a material you must test it to see if it will meet the standards. Some poeple test matrial for a living and it has help how are roads and briges are build today.
The math behind

The formulas we used are:
- Strain= Amount of stretch/Orignal length
- Stress= load/Area(cross section)
- modulus of elasticity= Stress/strain
After test

X axis= force
Yaxis= Elongation
max Strain =1.5-.183/1.5=.878psi
max Stress= 445/.013= 34,230.76 psi
Modulus=34,230.76/.878=38,987.psi

Most engineers use this to test material before they actually get material to the market. People test materials for a living. I believe that's why we need to know this. This activity wasn't so hard. Just using the lath machine was a new experience. I now know to test a material before using it.
