Consider the basic EOQ model. We want to know the sensitivity of (1) the optimal order quantity, (2) the sum of the annual order cost and the annual holding cost (not including the annual purchase cost cD), and(3) the time between orders to various parameters of the problem. a. How do (1), (2), and (3) change if the setup cost K decreases by 10%? b. How do (1), (2), and (3) change if the annual demand doubles? c. How do (1), (2), and (3) change if the cost of capital increases by 10%? (For this part, assume that the storage cost s is zero.) d. How do (1), (2), and (3) change if the changes in parts a, b, and c all occur simultaneously?
A string is stretched so that it is under tension and is tied at both ends so that the endpoints don't move. A mechanical oscillator then vibrates the string so that a standing wave is created. The dark line in each diagram represents a snapshot of a string at an instant in time when the amplitude of the standing wave is a maximum. The lighter lines represent the string at other times during a complete cycle. All of the strings are identical except for their lengths, and all strings have the same tension. The number of nodes and antinodes in each standing wave is different. the lengths of the strings (L) and the amplitudes at the antinodes (A) are given in each figure. А В A = 12 cm L= 25 cm A = 12 cm L= 28 cm C D A= 18 cm L= 27 cm A = 16 cm L= 28 cm Rank the frequencies of the waves. Enter in the form A > B = C ... make sure you separate characters with a space. Equal values can be entered in either order. Hint, the tension is the same so the velocity will be the same. Frequency is…
a) b) You want to know the temperature of the receiver after 8 hours of night time have passed (in the conditions described in the previous question). What technique would you use to determine this temperature? General lumped capacitance or 1-D transient analysis? Why?
