The strength coefficient (K) and the work hardening exponent (n) for a stainless steel were determined during the analysis of the data from a tensile test using a standard tensile specimen. The flow curve parameters for the stainless steel are K= 1250 MPa and n = 0.4. A compression test is performed on a specimen of the stainless steel. If the starting height and diameter of the specimen are 80 mm and 18 mm, respectively and the final height of...

Kristen is thinking about buying an expensive sports car to replace the car she bought last year. She would drive the same number of miles regardless of which car she owns and would rent the same parking space. The sports car’s variable operating costs would be roughly the same as the variable operating costs of her old car. However, her insurance and automobile tax and license costs would go up. What costs are relevant in estimating the incremental cost of...

Consider the two firms engaging in the Bertrand competition. On the demand side the market demand equation is p=200-Q. Consumers only buy from the firm charging the lower pric When charging the same price, they share the market equally. On the supply side, they have different marginal costs, with MC1=60 and MC2=50, and there is no fixed cost. Find the market price and the winner’s profit at the equilibrium. a. At the equilibrium the market price is 60 and the...

A smaller ball (mass m1) is aligned slightly above a larger ball (0.63 kg), and the two are dropped simultaneously from a height of 1.8m. (a) Draw a (i) before/after sketch and (ii) momentum & energy bar diagrams of the situation. (b) If the larger ball rebounds elatically from the floor and then the small ball rebounds elastically from the larger ball, what value of m results in the larger ball stopping when it collides with the small ball? (c)...

A student wanted to study the ages of couples applying for marriage licenses in his county. He studied a sample of 96 marriage licenses and found that in 67 cases the husband was older than the wife. Do the sample data provide evidence that the husband is usually older than the wife among couples applying for marriage licenses in that county? Explain briefly and justify your answer using the methods studied in this course. Use α= 0.05 as the level...

In a solar water heater, energy from the Sun is gathered by water that circulates through tubes in a rooftop collector. The solar radiation enters the collector through a transparent cover and warms the water in the tubes; this water is pumped into a holding tank. Assume that the efficiency of the overall system is 12.0% (that is, 88% of the incident solar energy is lost from the system). What collector area is necessary to raise the temperature of 260...

In November 2010 Netflix announced a new lower price for streaming video direct to home televisions. At the time, Netflix had no serious competitors- Netflix's share of the digital download market was more than 60% (the second firm's was only 8%). Just three months later, Amazon announced that it was entering the market for streaming video. How are these two announcements related?

A machine which has been classified as property,plant and equipment (IAS 16) and measured using the cost model has a correctly calculated carrying amount of N$50 000 immediately before being classified as 'held for sale'. On thew date of classification, it has a fair value of N$75 000 and estimated costs to sell of N$15 000. The transfer to the held for sale classification will result in the following:
