Quiz Instructions
Use any size of clean sheets of bond paper. Write your solutions neatly and legibly on one side only. You are given 150 minutes to answer the quiz from 12:00NN to 2:30 PM. In your COMPUTATIONS, use
THREE decimal places in all your computations (except for strain-use EIGHT decimal places). Input all your numerical answers in the text box provided in each number using THREE decimal places except as
indicated in the problem. No need to type the unit and the sign, only the numerical value of your answer.
Example:
If your answer is -235.234 kN.m, then type 235.234
If your answer is 1.886 MPa, then type 1.886
After submitting the quiz, you can start uploading the PDF or image copy of your solutions in the assignment created. Make sure the file is readable. The numerical answers encoded in the quiz will be matched
to the uploaded solutions. No solutions, no credit. If you find difficulty in uploading the files, kindly send your solution sheets through the inbox or FB chat. You are given 15 minutes only after quiz submission to
upload your solutions.

Question 1 pts
An aluminum rod has a diameter of 10 mm and a length of 800 mm. If an axial tensile force of 200 kN is applied to the rod, determine the final diameter of
the rod in mm if Eal = 70 GPa and al= 0.35. Use 5 decimal places for the value of strain in your calculations.
Correct!
9.873
Correct Answers 9.873 (with margin: 0.05)
