Imagine you’ve just had a container of televisions shipped to Los Angeles from Japan via ocean liner. You need to get the shipment to a distribution center in New York. How do you do this? Truck all the way? Rail? Air? How would you transport the shipment and why? In this assignment you will create a storyboard that depicts your containers’ journey from Japan to the distribution center in New York. You will analyze the advantages and disadvantages of each of the shipping methods discussed in this lesson in order to determine the best shipping method for your containers. Your storyboard should consist of multiple modes of transportation. For each leg of the journey, you will map out a realistic route for your cargo based on existing waterways, railroads, roads or airplane flight paths.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg. a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
