You are given an aluminium thick cylinder with outer diameter of 50 mm and unknown inner diameter and thickness. A strain gauge is set along the longitudinal axis and is equal to 500×10-6 when the thick cylinder is being applied the pressure of 39 MPa. With the provided material properties of E=69 GPa and ν=0.3, determine:(a) The inner radius and thickness.

(b) All hoop stresses and plot the hoop and radial stress distribution along the thickness (inner to outer radius).
