Q11 a) What is the basis for piston rod design? Explain the significance of area ratio.

b) List 4 of the likely causes for slow or erratic motion of an actuator in a hydraulic equipment.

A piston contains 620 moles of an ideal monatomic gas that initally has a pressure of 2.92 × 105 Pa and a volume of 4.1 m3. The piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir. The pressure of the gas is increased to 5.92 × 105 Pa while maintaining a constant volume. The volume of the gas is increased to 11.1 m3 while maintaining a constant pressure. The pressure of the gas is decreased to 2.92 × 105 Pa while maintaining a constant volume. The volume of the gas is decreased to 4.1 m3 while maintaining a constant pressure. It may help you to recall that CV C V = 12.47 J/K/mole and CP C P = 20.79 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas. 1) How much energy is transferred into the gas from the hot reservoir?

find two articles describing firms’ use of a cooperative strategy: one where trust is being used as a strategic asset and another where contracts and monitoring are being emphasized. What are the differences between the managerial approaches being used in the two companies? Which of the cooperative strategies has the highest probability of being successful? Why?

39. Tech is playing State in the last conference game of the season. Tech is trailing State 21 to 14 with 7 seconds left in the game, when they score a touchdown. Still trailing 21 to 20, Tech can either go for two points and win or go for one point to send the game into overtime. The conference championship will be determined by the outcome of this game. If Tech wins they will go to the Sugar Bowl, with a payoff of $9.2 million; if they lose they will go to the Gator Bowl, with a payoff of $1.5 million. If Tech goes for two points there is a 30% chance they will be successful and win (and a 70% chance they will fail and lose). If they go for one point there is a .98 probability of success and a tie and a .02 probability of failure. If they tie they will play overtime, in which Tech believes they have only a 20% chance of winning because of fatigue. a. Use decision-tree analysis to determine if Tech should go for one point or two points. b. What would Tech’s probability of winning the game in overtime have to be to make Tech indiff erent between going for one point or two points?

A game is played as follows. There are 2 goats and 1 car, each hidden behind a numbered door. You choose a door (for simplicity you always choose door 1) and then Monty Hall opens one of doors 2 or 3.The door that he opens always reveals a goat. Now Monty offers you to switch yourchoice of doors

(a) What is the probability that you win the car by switching your choice? Hint: Consider the events {Ci= car is behind doori} and use the first Bayes formula

(b) Explain the paradoxical result from part (a). Why is it >1/2?

(c) Now suppose that if Monty has to choose between opening doors 2 or 3 (i.e.the car is in door 1), he chooses door 2 with probability p ≥ 1/2. What is the probability that the switching strategy wins the car given that Monty opened door 2?Hint: Let D2 be the event that Monty opens door 2, then P (winning|D2) =P(C3|D2). Now apply the second Bayes formula.

The mean cost of domestic airfares in the United States rose to an all-time high of $370 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $120. Use Table 1 in Appendix B.

a. What is the probability that a domestic airfare is $550 or more (to 4 decimals)?

b. What is the probability that a domestic airfare is $245 or less (to 4 decimals)?

c. What if the probability that a domestic airfare is between $320 and $480 (to 4 decimals)?

d. What is the cost for the 5% highest domestic airfares? (rounded to nearest dollar)

The mean cost of domestic airfares in the United States rose to an all-time high of $400 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $120. Use Table 1 in Appendix B.

  What is the probability that a domestic airfare is $530 or more (to 4 decimals)?
