In a thick cylinder experiment the hoop and longitudinal strains on the outer surface were measured by strain gauges and found to be 250 x 10-6 and 65 x 10-6 respectively when an internal pressure of 100 mpa was applied. (3.1) calculate the actual hoop and longitudinal stresses on the outer surface of the cylinder. (3.2) if the outer diameter of the cylinder is 100 mm and the thickness is 25 mm, compare the theoretical values of the hoop and radial stress on the outer surface with the actual values and calculate the theoretical maximum hoop stress induced in the cylinder. (3.3) assuming that there is no applied shear stress, calculate the theoretical maximum shear stress induced on the inner surface of the cylinder.
