Question 3 (20 marks) As shown in the below figure, a filament-wound cylindrical pressure vessel of mean diameter d=1m and wall thickness t=20mm is subjected to an internal pressure, p. The filamentwinding angle =53.1 from the longitudinal axis of the pressure vessel, and the glass/epoxy material has the following properties: E1=40GPa,E2=10GPa,G12=3.5GPa, and v12=0.25. By the use of a strain gage, the normal strain along the fiber direction is determined to be 1= 0.001. (a) Determine the internal pressure in the vessel. (b) A tensile test specimen is cut out along the x direction of the pressure vessel. What effective modulus of elasticity, Ex, would you expect to get during a test of this specimen
