In an experiment on a thick cylinder of 100 mm diameter and unknown internal diameter, the hoop and longitudinal strain as measured by strain gauges applied to the outer surface were found to be 210 x 106 and 54 x 10 respectively. For an internal pressure of 88 MPa, an external pressure of 0 MPa, determine: E = 201 GPa Note: Give your ALL your answers to 3 significant figures. (i) The hoop stress H V = 0.29 Number Correct response: 49,500,000 Pa 0.5% Hint: The Lame equations should not be used, you should use simultaneous equations to solve for H Units (ii) The longitudinal stress o Number Units 3 Correct response: 25,200,000 Pa 0.5% Hint: The Lame equations should not be used, you should use simultaneous equations and your answer from (i) to solve for o (iii) The Lame constant A Number Correct response: 24.8 0.5% Hint Consider how your answers from (i) & (1) can be used with the Lame equations (iv) The Lame constant B Number Correct response: 0.0619 0.5% (v) The internal diameter d Number Units Correct response: 0.0469 m 0.5% x In an experiment on a thick cylinder of 100 mm diameter and unknown internal diameter, the hoop and longitudinal strain as measured by strain gauges applied to the outer surface were found to be 210 x 106 and 54 x 10 respectively.
