EXPERT ANSWER a) b)

EXPERT ANSWER

## 2 points The formula shown can be used for finding relative rotation of a segment of a tapered shaft. T(X2-X1) = 02-01 GJ O True O False 2 points Bending normal stress varies linearly across the cross section for a non-homogenous material. O True O False 2 points By inspection determine the bending normal stress at A. A B O Tension O Compression 3 3 O Zero The internal shear force jumps by the value of ponte the applied transverse force as one crosses it from left to right. True O False 4 니 2 points The formula shown can be used to find the normal stress on a cross section of a tapered beam. xx -My/I. O True O False 2 points By inspection determine the bending normal stress at B. DIII A B Tension ооо O Compression 6 Zero 2 points Bending normal strain varies linearly across the cross section for a non-homogenous material. O True O False 그 7 2 points The equations shown cannot be used for non-linear materials. jCxxdA = 0 and M. = -[YO.xdA A True 8 к O False 2 points Ductile materials show large elastic deformation but small plastic deformation before fracture. O True O False 7 2 points In the formula shown, y is measured from the bottom of the beam. 0 -M.y/1.. XX O True 10 O False

EXPERT ANSWER 1. True. This formula is valid 2. True. 3. Compression. Because the beam will be sagging, and in sagging top fibre is in compression. 4. True 6. Compression. This is hogging condition. Here bottom fibre is at compression. 7. True 9. True 10. False. y is taken from neutral axis. there is no …

## ACTIVITY 6.1: Player’s records using linked list Redo your work in Laboratory Activity 3 where you will record and compute for the scores of 5 players, this time, using linked lists. The information of each player contains: Nickname, Age and two best played scores. The program will prompt the user to choose the operation of records from a menu as shown below: MENU 1 1. Add record 2. View player’s records 3. Compute for the average 4. Show the player(s) who gets the max average. 5. Show the player(s) who gets the min average. 6. Exit VII. QUESTION AND ANSWER Briefly answer the questions below. Avoid erasures. For group activity, specify the name of GROUP MEMBER/s who answered the question. Do not forget to include the source for all NON-ORIGINAL IDEAS. What are the advantages of using linked lists? What are the disadvantages of linked lists?
