Sheet1 Page 1 Strength of Materials Quizzes EGR 283 Quiz #1 Solution All results must be given to the precision used in the textbook. Assume that the data are known to the same precision. Thus, when a value of 2 kips is given, it is assumed that it is known to 3-digits i.e., 2.00 kips. Units must be given with all answers. Print this page and write the answers in the blanks. Sign the statement at the bottom. Then submit the page before class on Wednesday. 1. What is the normal stress in a link of rectangular cross section (1.5 inches x 1/2 inch) if it is subjected to an axial force of 2 kips?2.67 ksi
