Chapter 13, Problem 13.57P
Interpretation Introduction

Interpretation:

The reason for the greater tensile strength of a bar of gray iron of class 40 than given by the class number is to be explained. Also, the diameter of the test bar is to be determined.

Concept introduction:

Grey cast iron is composed of small graphite flakes which are interconnected to each other causing the low strength and ductility of the cast iron. It is named grey cast iron due to the dull grey color of its fractured surface.

OK i need help. Please help me work thorought this with autocad. I am not sure where to begin but i need to draw this.  Well if you read the question we did it in class and I got suepr confsued.
Write a C program using embedded assembler with a function to convert a digit (0 – 15) to the corresponding ASCII character representing the value in hexadecimal. For numbers 0 – 9, the output will be the characters '0' – '9', for numbers 10 – 15 the characters 'A' – 'F'. The entire core of the program must be written in symbolic instruction language; arrays may not be used. You may only use C to print the result. Tip: This piece of C program will do the same thing: character = number < 10 ? number + '0' : number + 55; As a basis, you can use this program again , which increments a variable. Just replace the INC instruction with ADD and add a test (CMP) with some conditional jump.
A square column foundation has to carry a gross allowable load of 2005 kN (FS = 3). Given: D₤ = 1.7 m, y = 15.9 kN/m³, 0' = 34°, and c' = 0. Use Terzaghi's equation to determine the size of the foundation (B). Assume general shear failure. For o' = 34°, N₁ 36.5 and Ny = 38.04. (Enter your answer to three significant figures.) B=2.16 m
