1. An FCC aluminum polycrystal with 12 slip systems is loaded in tension. (hint: you have to figure out local direction of each grain to get loading direction that is shown as arrow)
a) Which grain will yield first when it is loaded in vertical direction figure 1a?
b) Which grain will yield first when it is loaded in horizontal direction figure 1b?

Problem 1 (10 pts) It is required to manufacture a 2.5 mm diameter copper rod from larger diameter stock by drawing. The rod should have a tensile strength of 300 MPa or more, a yield strength of 200 MPa or more, and ductility of 10% or more. Determine (a) the range of%CW which will allow achieving those properties, and (b) within this range clearly pick a certain%CW and determine the corresponding diameter of the starting stock. yield strength (MPa) tensile...

12. A longitudinal standing wave can be created in a long, thin aluminum rod by stroking the rod with very dry fingers. This is often done as a physics demonstration, creating a high-pitched, very annoying whine. From a wave perspective, the standing wave is equivalent to a sound standing wave in an open-open tube. In particular, both ends of the rod are anti-nodes. What is the fundamental frequency of a 2.50 m -long aluminum rod? The speed of sound in...

Game Description: Most of you have played a very interesting game “Snake” on your old Nokia phones (Black & White). Now it is your time to create it with more interesting colors and features. When the game is started a snake is controlled by up, down, left and right keys to eat food which appears on random locations. By eating food snake’s length increases one unit and player’s score increases by 5 points. Food disappears after 15 seconds and appears...

The following guidelines outline the basic template for a robot vacuum cleaner game. The game must be implemented in c programming language. It mimics a robotic vacuum cleaner. The code must only use the following libraries: #include <math.h> #include <stdlib.h> #include <string.h> #include <limits.h> and any .graphics and .timers libraries. The guidelines are outlined as follows: Terminal Set-up: you may assume that the terminal will be quite large, for example, on the order of 150×50, or more. Status Display: The...
