Chapter 1, Problem 58SDP
Take a deck of playing cards, place a rubber band around it, and then slip the cards against each other to represent Figs. 1.6a and 1.7. If you repeat the same experiment with more and more rubber bands around the same deck, what are you accomplishing as far as the behavior of the deck is concerned?

1) Draw (using a normal graph paper) a conventional
stress-strain diagram for ANY metallic material (e.g. steel,
aluminium, copper, brass, iron, tungsten). The diagram
should be as accurate as possible using a suitable scale
(e.g. 1cm: 10 N).
2) Calculate the Modulus of Elasticity, Modulus of
Toughness and Modulus of Resilience for the material
from the stress-strain diagram. Show your calculations in
detail on a separate A4 piece of paper.
The graph below gives a plot of force versus total sample length in a tensile test of a polymer. The sample is cylindrical, with an initial diameter of 1 cm and an initial length of 10 cm. From the data below, calculate the modulus, yield stress, yield strain, tensile strength, and % elongation.
(a) Find the relationship between δ1, the elongation of rod (1), and the internal tensile force, F1, in rod (1). Assume δ1 is a positive value in units of mm and F1F1 is a positive value in units of kN. So, the answer you enter for the ratio (δ1/F1) must be in units of (mm/kN).
(b) Similar to the previous step, find the relationship between δ2, the elongation of rod (2), and the internal tensile force, F2, in rod (2). Assume δ2 is a positive value in units of mm and F2 is a positive value in units of kN. So, the answer you enter for the ratio (δ2/F2) must be in units of (mm/kN).
(c) Similar to the previous step, find the relationship between δ3, the elongation of rod (2), and the internal tensile force, F3, in rod (2). Assume δ3 is a positive value in units of mm and F3 is a positive value in units of kN. So, the answer you enter for the ratio (δ3/F3) must be in units of (mm/kN).

A test specimen is placed between two clamps and these clamps will move in opposite directions, hence straining the test specimen. This experiment will yield a stress-strain curve that shows each of the stages of the specimen for every load is applied. With an aid of sketching diagrams, describe the stages that the specimen experiences before it breaks, and relate it with the stress-strain curve.
