Explain why small-angle grain boundaries are not as effective in interfering with the slip process as are high angle grain boundaries.

Question

A simply supported beam for a building interior with 18 ft span has a cross section of 12 in width and 21 in overall depth. The beam is made with 5 ksi compressive strength concrete and 60 ksi reinforcing steel. The beam supports a uniform service superimposed dead load of 1.6 kip/ft, and a uniform service live load of 80 psf throughout the span. The beams are laterally spaced 20 ft apart c/c. Design this beam and show in a sketch.

Ternary Phase Diagram+ Material balance One thousand kg/h of a (50-50 wt%) acetone-in-water solution is to be extracted at 25C in a continuous, countercurrent system with pure 1,1,2-trichloroethane to obtain a raffinate containing 10 wt% acetone. Using the following equilibrium data, determine with an equilateral-triangle diagram: a- the minimum flow rate of solvent; b- the number of stages required for a solvent rate equal to 1.5 times minimum, and composition of each streamleaving each stage. c. Repeat the calculation of (a) and (b) if the solvent used has purity 93wt% (4wr% acetone, 3wt% water impurities) acetone water 1,1,2-trichloroethane Raffinate. Weight Extract.

Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.
