60. [-/0.5 Points] DETAILS WANEFMAC8 12.2.028.EP. Worldwide annual sales of a product in 2013-2017 were projected to be approximately $q = -10p + 4,440$ million units at a selling price of $p per unit. Find the function $R$ for projected revenue, in millions of dollars and in terms of $p$ only, subject to any constraints. $R(p) =$ Find $R'(p)$. $R'(p) =$ What selling price (in dollars) would have resulted in the largest projected annual revenue? $p = $ What would have been the resulting projected annual revenue (in millions of dollars)? $\$ million

1. For the schematic of the disk shaft system shown, assume the pillow blocks constrain the bending of the shaft (as opposed to pinned joints) so bending deflection approaches PL³/192EI. Assume the hollow cylindrical shaft is massless steel with outside diameter of 2 in. and a wall thickness of 1/8th of an inch. The disk weighs 322 lb. The distance between the supports is 37 in. The steady state speed (or running speed) is 3600 rpm. The machinist was in a hurry and so the centerline offset of the disk, a, is 0.006 in. Let zeta be .025. ? Shaft Support bearing Disk Support bearing 40 pts. Find the critical speed of the rotor. 10 pts. Find the value of the r-ratio at the steady state speed. 10 pts. Find the amplitude of whirl at the running speed? 5 pts. Find the whirl amplitude at the rotor's critical speed.

6. A 4 pole DC shunt generator with wave wound armature having 390 conductors has to supply a load of 500 lamps each of 100W at 250 V. Allowing 10 V for the voltage drop in the connecting leads between the generator and the load and brush drop of 2V. Calculate the speed at which the generator should be driven. The flux per pole is 30mWb and Ra = 0.05 ohms and Rsh = 65 ohms.

E6-16 Inventory methods [10-15 min] Express Lane, a regional convenience store chain, maintains milk inventory by the gallon. The first month's milk purchases and sales at its Freeport, FL, location follows: Nov 2 1 gallon @ $2.00 each 6 2 gallons @ $2.10 each 13 2 gallon @ $2.20 each 14 The store sold 4 gallons of milk to a customer. Requirement 1. Describe which costs would be sold and which costs would remain in inven- tory. Then, identify the amount that would be reported in inventory on November 15 using a. FIFO. b. LIFO. c. average cost. E6-17 Measuring and journalizing inventory and cost of goods sold in a perpetual system—FIFO [20-25 min] Golf Haven carries an inventory of putters and other golf clubs. Golf Haven uses the FIFO method and a perpetual inventory system. The sales price of each putter is $128. Company records indicate the following for a particular line of Golf Haven's putters: Date Item Quantity Unit Cost Nov 1 Balance 17 $68 6 Sale 7 8 Purchase 20 $74 17 Sale 20 30 Sale 4 Requirements 1. Prepare a perpetual inventory record for the putters. Then determine the amounts Golf Haven should report for ending inventory and cost of goods sold using the FIFO method. 2. Journalize Golf Haven's inventory transactions using the FIFO method. E6-18 Measuring ending inventory and cost of goods sold in a perpetual system—LIFO [20-25 min] Refer to the Golf Haven inventory data in Exercise 6-17. Assume that Golf Haven uses the perpetual LIFO cost method. Requirements 1. Prepare Golf Haven's perpetual inventory record for the putters on the LIFO basis. Then identify the cost of ending inventory and cost of goods sold for the month. 2. Journalize Golf Haven's inventory transactions using the perpetual LIFO method.

A U shape conducting frame has a conducting rod that can slide on the frame. There is a uniform magnetic field, $B_0$, going through the entire area of the frame that is perpendicular to the plane of the frame. The conducting rod of length D and is being pulled along the frame by a force $F_0$ at a constant speed S. The mass of the rod is M. What is the resistance of the rod? Assume the resistance of the conducting frame is negligible, the surfaces are frictionless, and that any induced magnetic field is much less than $B_0$ and can be ignored. \begin{itemize} \item $\frac{B_0^2 D^2 S}{F_0 - Mg \sin \theta}$ \item $\frac{B_0^2 DS}{F_0 + Mg \cos \theta}$ \item $\frac{B_0^2 D^2 S}{F_0 - Mg \cos \theta}$ \item $\frac{B_0^2 DS}{F_0 - Mg \sin \theta}$ \item $\frac{B_0^2 S}{F_0 - Mg \sin \theta}$ \item $\frac{B_0^2 DS}{F_0 - Mg \cos \theta}$ \item $\frac{B_0^2 S^2 M}{F_0 - Dg \sin \theta}$ \end{itemize}
