HW1
The following data were obtained from a tensile test on a specimen of
10 mm diameter and gauge length 60mm , the diameter after fracture was
7mm . Using the graph paper supplied, plot the load-extension diagram and
then
1- Plot the data as engineering stress versus engineering strain.
2- Determine Young Modulus
3- Determine the yield strength at a strain offset of 0.002.
4- Determine maximum tensile strength of this alloy.
5- What is the approximate ductility?
