N 8 3 I w 16 Answer Question 2 (15 points) Consider the same circular plate, as in the previous question, and consider a plate thickness of h=120mm. Also, assume that the plate is made of a material that has a Young's modulus E-82 GPa and a Poisson's ratio 1-0.26, respectively. Workout the value of the flexural stiffness (flexural rigidity) D in GN.m (GN.m-10⁹ N.m) (Hint: round your answer 4 digits after decimal point))? Your Answer: P Lr> Ro
age 1: D 2 3 IN 1 5: 6 8 19 -- Question 3 (15 points) The same circular plate, as in the previous questions, is considered and a radius of Ro-330mm is assumed. Also, assume that the plate flexural stiffness is D-1.2 x 105 N.m and that the plate is subjected to a uniform pressure of P-100 kPa. Find the absolute value of the maximum displacement (in mm) of the plate. NOTE: type in your answer without considering any negative sign. (Hint: round your answer 4 digits after decimal point))? Your Answer: P Ro
2 3 6 9 Question 4 (20 points) The same circular plate, as in the previous questions, is considered and a radius of Ro=320mm is assumed. Workout the location (i.e. the radius r in mm) at which the maximum slope takes place. NOTE: round-off your answer to four decimal places. Your Answer: Lr P Ro
2 - 5 3 16 9 -- Question 5 (15 points) The same circular plate, as in the previous questions, is considered. Assume a plate radius of Ro=400mm and a plate thickness of h-7.74mm, respectively. Also, assume that the plate is subjected to a uniform pressure of P-1,960 KPa, and that the plate is made of a material of Poisson's ratio V-0.40. Find the absolute value of the radial stress at the centre of the plate in KPa. NOTES: type in your answer without considering any negative sign; round-off your answer to 4 decimal places. Your Answer: P Ro
3 5 Question 6 (5 points) For a simply supported circular plate, which of the following is NOT correct. Select 2 correct answer(s) The radial stress at the edge is zero. The circumferential stress at the edge is zero. The radial bending moment at the edge is zero. The slope at the edge is zero Question 7 (5 points)
3 6 9 Question 7 (5 points) The circumferential stress at the edge of a simply supported circular plate, which is subjected to a concentrated force at the plate centre, is: Undefined Maximum O is larger than the radial stress Zero
Question 8 (5 points) For a fixed circular plate under a uniform pressure, the edge radial stress (i.e. the radial stress along the circumference of the plate) is always zero. True False
ge 1: 2 5 8 3 9 9 Question 9 (5 points) Which of the followings is NOT correct: For a fixed plate under uniform pressure, the plate radial stress is always compressive. For a simply supported plate under concentrated force at centre, the radial stress at the centre is discontinuous. The constants C2 and C3, which appear in the differential equation associated with the deformation of a plate, are zero for both fixed and simply supported circular plates. For a fixed plate under uniform pressure, the absolute value of the maximum radial stress is always higher than the circumferential stress at the plate edge.
