A cylinder(σY= 230 MPa)which is initially free from residual stress has internal radius b = 20 mm and external radiusa= 50 mm. Determine:

a)The maximum internal pressure without yielding the cylinder. Give your answer in MPa.[5 marks]

b)The fully plastic internal pressure. Give your answer in MPa.[5 marks]c)The radius to which the material yields, when the pressure is 150 MPa. Give your answer in mm.[10 marks]

c)The cylinder is loaded by internal pressure, pi, which, when released, causes residual stress in the hoop direction of-0.5σYat the internal radius.

Determine:d)The internal pressure,pi.Give your answer in MPa.[25marks]
