Suppose that you have a metal paper clip that you bend over and over in the same spot. Draw a stress-strain plot for this experiment and label each part of the curve with its rheological phase or property. Describe what happens during the experiment in terms of stress you apply, strain achieved, and what the metal is doing internally to heal itself during the process. Name the term for this process and describe how it is used historically and today to forge metal.

Expert Solution

here is the graph below. the different parts of the graph are like that

proportional limit

From the origin O to the point called proportional limit, the stress-strain curve is a straight line ,within the proportional limit, the stress is directly proportional to strain .

Elastic Limit
The elastic limit is the limit beyond which the material will no longer go back to its original shape when the load is removed, or it is the maximum stress that may e developed such that there is no permanent or residual deformation when the load is entirely removed.

Yield Point
Yield point is the point at which the material will have an appreciable elongation or yielding without any increase in load.
Ultimate Strength
The maximum ordinate in the stress-strain diagram is the ultimate strength or tensile strength.

Rapture Strength
Rapture strength is the strength of the material at rupture. This is also known as the breaking strength.

For this activity you will need a fresh lemon, a metal paper clip and a small piece of copper wire. You may use different metals as long as the two metal pieces used are different. Insert the two pieces of metal into the lemon through the rind. The metal should not be touching but close enough for your tongue to touch both. Describe what happens when you touch both metal pieces with your tongue. This cell is described further in...

In a sample of 200 Bend households, you nd that 110 have cable television. In a sample of 250 Portland households, you nd that 160 have cable television. You wish to know whether these data indicate that the percentage of Bend households (population 1) with cable is less than the percentage of Portland households (population 2) with cable. Use = 0:05 in the hypothesis test. 1. Set up the null and alternative hypotheses and perform test statistics using normal model. 2....

Over the eight weeks of the course, you will work on a paper that addresses a current controversial issue. This paper is to be in the form of an argument. You will select a topic, choose an issue related to that topic, thoroughly research both sides of the issue, and then write a paper that supports one side or the other of the issue. Your paper must define the issue, present evidence on both sides of the issue, and then...

Suppose you have two individuals in a town, Ben and Jerry, deciding over their consumption of ice-cream and fireworks. Further suppose that the price, as well as the additional cost of producing both goods is $1. Assume that Ben and Jerry have the same preferences. If we left it up to Ben and Jerry, would we get the optimal provision of fireworks? Explain and show your answer.

Hitchhikers thumb is an inherited trait in which a person can bend his/her thumb backwards over halfway past vertical. The trait is due to a recessive allele. (H = normal, h = hitchhiker’s thumb) 7. John and Joy met hitchhiking, attracted to each other by their hitchhiker’s thumbs. They are expecting their first child and hope that it will have hitchhiker’s thumb like both of its parents. What are the expected genotypic and phenotypic ratios for their offspring? 8. Chris...

Suppose a batch of metal shafts produced in a manufacturing company have a standard deviation of 1.5 and a mean diameter of 205 inches. If 79 shafts are sampled at random from the batch, what is the probability that the mean diameter of the sample shafts would differ from the population mean by less than 0.3 inches? Round your answer to four decimal places.
