You are going to make many cylindrical cans. The cans will hold different volumes. But you'd like them all to be such that the amount of sheet metal used for the cans is as small as possible, subject to the can holding the specific volume. How do you choose the ratio of diameter to height of the can? Assume that the thickness of the wall, top, and bottom of the can is everywhere the same, and that you can ignore the material needed for example to join the top to the wall. Put differently, you ask what ratio of diameter to height will minimize the area of a cylinder with a given volume? That ratio equals 1:2

2. Consider the incompletely specified function of 4 variables presented as a sum of minterms and don't cares: G (A, B, C, D) = ?(0, 1, 2, 7, 9) + d(5, 8, 11) Obtain the following a) K-map for function G(A, B, C, D). b) Use K-map to locate and list all prime implicants (P.I.) (a reminder - for the list of P.I.s all don't cares are treated as 1). c) Essential prime implicants (E. P. I.) (an EPI is a P.I. which includes at least one minterm which has no alternative coverage by other P.I.s). d) The minimal function cover for G in the SOP form (an algebraic expression with the minimum number of literals, obtain only the minimal expression in the sum of products form). e) For the minimal expression in d) identify the consensus term(s), if any.

A hemispherical tank of radius 2.8 m is full of water. Find the work done in pumping the water out of the top of the tank. (Hint: The weight of each element is 9800?\\ (radius)$^2$ (thickness), where the radius of each element is different. If we let x be the radius of an element and y be the distance the element must be raised, we have\\ 9800?x$^2$ dy with x$^2$ + y$^2$ = 7.84. In this way, the force, which is the weight of the element, and the distance through which the force acts are determined. Thus, the\\ products of force and distance are summed by integration.)\\ The work done is ? N \\· m.\\ (Use scientific notation. Round to two decimal places as needed.)

Partial data for a Philips ER35/21/11 ferrite core half is illustrated in Figure 2. Two of these core halves are placed together to form a closed magnetic path, with a winding encircling the center leg of the core set. The (Philips 3C90) material permeability is 19000, and the allowed flux density BS is approximately 0.35 T. A. Create a magnetic circuit model for a winding on this core set, including the reluctances of the main magnetic paths. (You need not consider "leakage flux traveling through the air.) B. Please find the specific inductance, AL, of the core set. AL is the number of nano-Henries for a single-turn winding. C. How many ampere-turns can be applied in a winding on the core without exceeding the maximum allowed flux density? D. What is the maximum (saturation) current limit for a 12-turn winding on the core? E. A 250 mm gap is now inserted in the center leg of the core set (by grinding down the center leg of one of the core halves). Find the inductance and maximum (saturation) current for this new configuration with a 12-turn winding. How does the total energy storage capability compare to the ungapped case?
