Challenge Problems
Push your limits with advanced challenges
Consider a thick-walled cylinder with an internal radius of 0.3 m and external radius of 0.4 m. If the internal pressure is 80 MPa, calculate the radial and hoop stress at the inner radius.
💡 Hint: Don't forget to use both equations for a complete understanding!
A boiler operates at a temperature that increases the thermal stress by 15 MPa and internal pressure adds 90 MPa of mechanical stress. What is the total stress on a critical component?
💡 Hint: Add the stresses carefully to get the total.
