A fluid has a volume of 8.7m^3 and a weighs 53500N. Determine its specific gravity Choices are: A. 0.63 B. 0.76 C. 0.89 D. 0.5

Figure Q5 shows a thick cylinder of [A] mm internal radius and [B] mm outer radius is subjected to an internal pressure of 60 MN/m² and an external pressure of 30 MN/m². Determine the hoop and radial stresses at the inside and outside of the cylinder together with the longitudinal stress if the cylinder is assumed to have closed ends using analytical and graphical approaches. Use 5th digit and 6th digit of your matrix number to get value of [A] and [B] as an example below: Example: If your matrix number is AD170128; Thus, the value of A=65 and B=160 : 5th digit of matric 6th digit of matric A В number number 50 100 1 57 1 107 65 115 3 72 3 122 4 80 4 130 87 137 6. 95 145 7 102 7 152 8. 110 8 160 9 117 167
