Question 1
What is the formula for hoop stress in thin-walled cylinders?
- σ_h = pt/r
- σ_h = p/rt
- σ_h = pr/t
💡 Hint: Look for relationships that involve pressure and radius.
Question 2
True or False: Axial stress is always greater than hoop stress in a thin-walled cylinder.

Challenge Problems
Push your limits with challenges.
Question 1
A thin-walled cylindrical tank has an internal radius of 5 m and a wall thickness of 0.1 m. If the internal pressure is 300 kPa, calculate the hoop and axial stresses.
💡 Hint: Ensure you maintain units consistent while substituting.
Question 2
A chemistry lab holds a thin-walled tube under a vacuum of 50 kPa. If the tube’s internal radius is 0.2 m and thickness is 2 mm, calculate the stresses considering it’s subjected to both internal and external pressures.
💡 Hint: Analyze each pressure separately before combining.
