A solid steel (E-207.000 MPA & V.3) piston rod of a high-pressure hydraulic actuator has a diameter of 25mm and a length of 380mm, of which 360 mm is exposed at the end stroke. The inside diameter of the cylinder is 65mm and the pressure is 100 Mpa. The outside diameter of the cylinder is 85 mm. deytinder dpiston p 140.83 MPa 321.73 MPa -40.06 MPa 425 MPa dROD Assume the cylinder housing is made of the same material as the rod and the pressure in the atmosphere may be negated. What is the longitudinal stress o experienced on the cylinder?
